Glock 35 --> 9mm conversion ?

[savasyn]

I just brought my new(to me) G35 home tonight. I instantly swapped all the lower internals over to G34 parts and a .40-->9mm KKM barrel that I had waiting for it. This is being built as my competition gun and will be going to Randall's tomorrow night for his sweet match trigger job

While I was cleaning out the striker channel, swapping the extractor and polishing the safety plunger, I noticed that the striker says "40" on it.
1) Is that a coincidence or are the strikers different in the .40 and the 9mm?

2) Instead of a normal spring holding the striker release up/back, it had a gray piece of plastic with a captured spring under it. Is this specific to the G35 or do all new Glocks have this type now? When I swapped ejector blocks, I tried it and a standard Glock spring and much preferred the standard.

3) I was under the impression that the G34/35 came with the 3.5lbs trigger bar installed, this one did not have it. Luckily, I had an extra. With everything polished up and the light bar in there, it already feels great.

4) As this will be my match gun and will be using it in 9mm mode 99% of the time, should I get a different recoil spring weight? I assume the .40 will be a bit strong for lighter loads. Is Glockmeister a good place to look for upgrades in this area?

5) What is the standard weight (in lbs) of a stock Glock 9mm recoil spring?

Thanks!

you didn't NEED to do that but since your using it for competition the once in a blue moon jam due to the .40 extractor/ejector is an issue.

I don't know *waits for someone who does*

I thought that too but aparently they don't since some 34's and 35s go to LEO's they can come with 5.5lb and ny1 and on and on to make em ungodly heavy.

as far as I know the 17,22,34,35 all use the same recoil spring. I'm sure there are other models that do as well but I'm not butch I'm not all knowing of all things glock.

4) Glock 34/35s come standard with a 19-lb uncaptured recoil spring. I swapped that out for a 13-lb captured recoil spring on my 34. I did this on the 35 when I had one. Yes, Glockmeister is a good place to look for it.

5) I think I answered this in the above answer.

What types of competitions are you going to use this for?

Actually the G34/G35 come with a captured recoil spring assembly, just like all Glocks. They both use the same spring, Glock #SP01533, this same part also is used for the 17, 22, 24, and 31.

As for the trigger spring/connector, check the label on the handle of the box it came in. That label should include the trigger pull as-shipped weight.

Thanks for all the info, guys! Good to know the stock spring will be ok until I can get a different one.

I bought it used and it didn't come with the original box. It felt very similar to the standard 5.5lbs trigger, though. Not anymore, though. It's now light and very clean

As to what kind of matches I'll be using it in, Action Pistol and 3gun.

Keep in mind that if you change the barrel to 9mm, it becomes illegal to use it in IDPA (I don't know about USPSA Production Division). For IDPA, the caliber you are shooting must match what is printed on the gun (or the model number).

Not sure anyone would ever say anything at a local match, but they might. And you would definitely get called on it at a large match.

I'm not too worried about it as I'm only shooting in local matches. Some day when I'm good enough to compete in something bigger, I'll worry about it then.

Yep, the 34 and 35 use the same recoil spring... and the Springfield XD-9 and XD-40 use the same recoil spring.... which makes me wonder what they are smoking.

Anytime somebody tells me a gun is sprung correctly using the same spings in both 9mm and .40 I usually think they are either foolish or just too lazy to get the correct spring..... and the aftermarket barrel makers who make the 9mm conversion barrels for the XD recommend going down to a 14# spring (the stock spring is 17#).

He could shoot ESP instead of of SSP - in SSP it does say you can't use a caliber that wasn't offered in the original factory model - with a Glock it's be some serious nitpicking for someone to complain because after all you can get Glocks in 9mm.

But if you shot ESP you'd be fine.

Actually, this is one of those semi-gray areas. A barrel caliber change is not included in the "PERMITTED Modifications" List for any of the divisions, which is inclusive. Supposedly, only modifications stated in that list can be made. Anything else is illegal.

I have the feeling that when the rulebook was written, they wrote the SSP list first, then didn't add some of the conditions to other divisions (i.e. the 2,000 unit production criteria should also be in Stock Service Revolver).

Glock 34's and 35's are ESP guns to begin with. I am not sure why they care about using a 9mm conversion barrel in a .40 S&W. I just wonder if the point of impact is the same as the 9mm as the .40. In a Sig P229, the 9mm conversion causes the point of impact to be lower.
