Advantage Arms .22 Glock Conversions

I see. I guess it is truly YMMV.

That said, not all Mini Mags works, at least for me... See my screenshot - am using the HP flavor.




True that... I had a bunch of Atlanta Arms ammo for steel challenge. I think it was so low recoil that my kid loved it. Wanted him to continue with it so he enjoy more in the local matches until he could step up to the required power factor. Unfortunately, Atlanta Arms stopped shipping to California. Oh well, reloading is the way - I have a 750 that I still have not opened in at least 2-years now.

I think AA recommends using the round nose and not the HP. My guess the HP might hang up on the ramp. Having said that even with round nose, I might get a failure once every other magazine with the round nose minimags. But I haven't really broken it in yet, so I'm optimistic that it will improve. I hope ...

Thanks for the feedback all.

Sounds like it really is hit or miss.

Good to know, I'll wait to get one until it goes on sale somewhere. Seen 'em for as low as $230.

yup, that is what AA recommends... but amazingly in my setup, the HPs are the ones proving reliable.

It?s fine if you keep try 750 unused. There?s already enough competition for components during shortage times

For what it?s worth, I?m using 115gn rn played, 3.9gn Titegroup loaded to 1.10?. It can cycle a stock G17 and it?s very easy to shoot

way more reliable trainer than AA 22lr kit in my opinion

LOL

No problem... I have also have the required components - 4-lbs of 9mm brass, 5K bullets, and 10-lbs of N320.

Thanks for the formula. I will keep a note of it.

Didn?t mention primers though? are you keeping your stash size secret so we don?t get jealous lol

Btw a friend just got a Glock 44 are really likes it. Good reliability across ammo brands and types. N=1 means nothing but I?m pretty interested in that as a trainer for noobs

bought an optic ready AA kit for my G17 and put around 300 rds using minimags without issues. Loving it!

Advantage Arms 22 conversion - hacks that seems to work

As previously mentioned in post #8 above, I purchased the AA conversion to go on a Glock 19 Gen 3. I initially lubed the unit and took it to the range with three or four different .22 cal brands. My unit actually prefers Blazer 40 gr RN and then CCI MiniMags as a second choice.

Once I chose an ammo, I ran 80 rounds (8 mags) and had 14 Failures To Feed (FTF) or about a 17.5% failure rate even while using my #1 Blazer ammo choice, which has less failures than other brands. Almost all of these were rounds doubling up or stove piping with a spent case not being extracted.

So, after a little Internet searching, I decided to polish up my internals using the two following links as informational sources:

https://www.youtube.com/watch?v=mOnBkubtKU8

https://www.glockforum.com/threads/partial-advantage-arms-eat-anything-polish-mod.7614/

In polishing the chamber, I used the same Mother?s polishing compound with about 8o pulls of a .22 cal bore snake.


(Note: To date, I have polished the barrel, barrel chamber, barrel carrier and area of the frame behind the carrier. I have yet to take a part the slide to get to the firing pin, extractor and safety.)

(Note: my unit works better wet than dry lube wise.)


After doing the polishing and running the gun clean and wet, I went back to the range, again used Blazer ammo with the following results: 2 FTF out of 200 rounds (20 mags) or about a 1% failure rate.

I ran another range trip of 50 rounds with the gun dry and dirty and had 2 FTF and 4 FTE or a 12% failure rate. These results led me to conclude that clean and wet is the way to go.

Next, after a little more Internet research, I decided to see if I could do even better by lubing the .22 rounds. To do this I used Hornady One-Shot on a shop micro-fiber rag ? not too much but enough to slightly dampen the rag. I then placed the .22 rounds on the rag and rolled them around.

With the "lubed" rounds and the gun clean and wet, I went back to the range and shot 129 rounds (almost 13 mags) with no FTFs but 1 failure to pick up a round out of a magazine. This equated to a failure rate of 1 out of 129 or 0.76%.

The next time I went back to the range I tried 59 rounds ?lubed? and 50 rounds without lubing with the following results: lubed was 1 failure to pick up in 59 rounds or 1.7%; non lubed was 3 in 50 rounds or 6%.

So overall, since polishing and having the gun clean and wet, I note the following results:

- using polished parts but no round-lubing, I shot 259 rounds or 26 mags with 2 FTF and 3 failures to pick up or a failure rate of 1.93%

- of the above and using round-lubing, I have shot 229 rounds or 23 mags with only 2 failures to pick up or 0.87%

- overall, 488 rounds fired in almost 49 magazines with only 7 failures or 1.43%.


Final thoughts - I realize that I need to shoot more rounds to see if the data continues to be duplicated but so far I am very happy with the results and dropping the failure rate from 17.5% to under 2%. It would seem that I have eliminated the FTFs and now I need to see if the failure to pick-up is specific to a particular magazine or not. Additionally, when I get time, I need to break the slide down and finish polishing the rest of the internals in the slide for good measure.

Overall, this kit is a good and cost-effective training tool. My only complaint at this point is that shot grouping is not as good as the factory barrel.

FWIW - Got one, took it to the range without any polishing or modifications.

Functioned flawlessly (about 150 rounds worth) using recommended CCI ammo: MiniMag, Blazer, and AR Tactical.

Happy with my purchase.

I found one of the problems with my 2 AA conversions (1 gen 3 and 1 gen 4) was they weren't going fully into battery. I found the slide wasn't closing all the way and rounds were getting light strikes and not firing, or detonating with the slide partially open (1 to 2 mm). The shell expands partially out of the chamber which prevents it from properly extracting. It's even difficult to remove with a screwdriver. No amount of parts polishing would fix the problem.

I figured it was a battle between the recoil spring and the striker spring (combined with the extractor spring force). Both uppers would work 100% if I manually pushed the slide forward into battery after each shot. Since the recoil spring is captive and changing the extractor spring would cause undue wear of the aluminum slide by removing and installing the steel roll pin, my only solution was to install a weaker striker spring. So I tested springs from 2.5 pounds to 6 pounds. I found the 4 pound spring worked the best. Any lighter and I'd get constant light strikes. Any heavier and the gap would reappear.

I now need to put more rounds through it with the 4 pound springs to see if that truly took care of my problems. I had to build my own test fixture to test striker springs, because I found the advertised weight of striker springs didn't always correspond with reality.

I had great success on a G19.3 with CCI Blazers, after a light but thorough application of Breakfree CLP.

If I can hop in here...


Today I took my new AA conversion kit for the XD9 to the range to just get an idea of what ammo it likes or hates.
It wasn't anything in-depth, just 30rds of 9 different ammo brands and I would keep tally on paper if any had a FTF or StovePipe.
The top four brands were: CCI Blazer 40gr RN (1FTF), Remington Golden Bullet 36gr HP (2FTF), CCI MiniMag 40gr RN (3FTF), and Aguila 38gr HP (3FTF/1SP).

spend a little more and buy a buck mark instead

Meh... my AA kit works just fine turns out. 150 rounds without a hitch.

Buckmark doesn't fit the holster I use and train with every day.
