View Full Version : So I decide to hacksaw the Compensator off my FRANKENGLOCK .357 SIG..!..

So as the years go by I end up with a bunch of GLOCK parts. Barrels, slides, internal parts. I decide since I have a Concealed Carry Permit that works in Nevada I would built a FRANKENGLOCK out of an older 2006 GLOCK 27 I own. So when I go to "Vegas Baby" next month I would have something interesting to pack. I decide to change the caliber to .357 SIG. I like the round and because it's a bottle neck it feeds very well.

I collect OD GLOCKS (like ex-wives) and while I do shoot a few of them (hehe), most are New In Box and have never been fired.

The Glocks I do shoot are very reliable and run 100%. This is true of my GLOCK 27 in .40 caliber.

I love the small Glocks like the 26 and 27. They are easy to conceal and can accomodate my hi cap prebans without problems. I have decided that the small Glocks like the 26 and 27 will be the smallest handguns I will carry. I don't want to break in a Kahr or a Ruger. I prefer to stick to this Glock platform that is 100% out of the box.

This is the FrankenGlock with the normal .40 barrel. Not bad.

I had an extra coated slide assembly (silver hard chrome) for the G27. I had a KKM threaded barrel with compensator in .357 SIG. I decided to built up the slide with original Glock parts and install this extra barrel. (and compensator; if I liked it I would TIG spot weld the comp to the barrel to avoid certain issues)

I did like the 'Look' of the compensator and after building this FRANKENGLOCK up from parts I took her to the Range at On Target. (my favorite place, in Laguna Niguel)

She felt good in my hand.

I had a couple of boxes of range ammo and a couple of boxes of Gold-dot 125 grain, 1350 FPS stuff...

While she shot straight and true, I had a big problem with failure to eject. Almost every other round of the range ammo failed to eject. Shooting the hi performance gold-dot it ran a bit better, perhaps 50% better. I decided that the stainless compensator was too heavy on the end of that long barrel. And would prevent the barrel from moving up and down during the aft slide motion. This in turn prevented the complete ejection of the empty .357 SIG case. Not acceptable.

So when I returned home out came the HACKSAW....A few minutes later and a bottle of cold water she was free.!

After a little polishing on the barrel end, she is now ready.

With the compensator :ack2: :cuss: :censored:

Without :D :) :43:

Did the comp even really help out anyways besides the fact that the gun wouldn't function?

Lumpia is sarap!

I thought NV no longer accepts out of state CCW permits?

How did you re-crown the barrel?

It would be interesting to get some groups with just a hack saw job and another after a recrown. I have always wondered just how much the crown effects accuracy. It looks like he did come polishing work to the front. KKM would be happy to recrown it for a fee but it would be done right.

Wow! You can't wait to find anyone with a lathe? ;)

I'm interested in how the accuracy is affected by the hacksaw job. Unless you cut it square and polished off the burrs then you may just done it right. Keep us posted.

What I want to know is whether the gun runs now that the compensator is removed.. Seems like an irreversible process all for not if the gun still fails to eject..

The only way I cut a barrel is to part it off on a lathe on a 3 jaw chuck, after indicating it true, if it won't run true, then I put it on a 4 jaw until it runs true, then cut the OD with a .125" radius tool and the same for the ID. No de-burring or polishing afterwards, shooting it will de-burr it. Accuracy can be greatly affected by the crown, but at close range it doesn't matter much.

I've cut a lot of rifle and pistol barrels over the years. In my shop (Reloading room) I have all the tools to do a good job.

http://i51.tinypic.com/2zhr33r.jpg

On the opposite wall I have a moveable table with 4 machines that cut, grind, polish and I even have a level surface plate. (steel). The wheels are 3M cutting wheels (Scotchbright, about $65 per wheel) that actually CUT metal and polish at the same time. After I cut the barrel with the hacksaw I pushed it against my stationary sander; then on to the ScotchBright wheel.

As you can see the barrel is cut perfectly and polished. I expect it to run as good as the others I have cut.. :cool2:

Thanks Ryan..!

Hi Voo...I bought the barrel with the Compensator already attached, used. I expect it to run like a normal barrel without all that weight out front. I will be shooting a quick 150 rounds later this week. I still have the Compensator, But it is a KKM labeled 9MM/.357 SIG. So I doubt I will use it on anything. These comps do work on 10MM, mainly because that round has the power to move that slide with plenty of force...hehe. Not so on the 9 or .357 my friend.

I see a lot of glock boxes!!

Hi Richie....Those boxes are empty. The 18 Glocks they represent are in my Safe. (Or over at my Adult Son's house)

Cool.

Actually I think that is a rumor. (perhaps Utah..?)...Not Nevada.

Here is the latest info. I have an Arizona Non resident permit. Nevada has already issued a ruling that after July 1st Arizona permits are good...!

I didn't notice any difference. I am not recoil sensitive and I shoot mostly 10MM hot loads in my Glock 20s and 29s. Shooting .357 SIG is easy as pie. A very sharp snap and a fast moving bullet. Much less recoil than my Smith Model 66 .357 magnum.....:)

I've ran into several CAL GUNs members over at ON TARGET..and let them all shoot my Glock 29, 10MM. To a man, they were all surprised at how accurate and easy it was to shoot. :D

Guns recoil...don't pay attention to it.

Be well
Bob

Nice Two-tone! That comp didn't do that LTC-grade Glock any good anyhow. Looks like it would snag on clothing getting drawn out, with the gap between comp and slide being that big, imo.

This is a legitimate question and not a dig at you, but how is just polishing the cut end the same thing as crowing the barrel?

For recrowning a barrel all you need is valve lapping compound and the rubber ball from your computer mouse. Coat the ball with the compound, push the barrel into it and roll the ball in a figure 8 until you get the crown you want. Cheap and works great.

You can also use a brass pan head screw and a drill press , but sometimes speed is the enemy.

Wow, that turned out pretty good! I had the same set up with my barrel and was planning to do the same thing. But as you know it bills came around and had to sell it.
