Glock 23 with .357 barrel

[armed1]

Is it OK to drop a .357 barrel into a glock 23? Will the added pressure and recoil wreck the gun?

[azdave12]

As long as the frame is THIRD generation, NO problem....the 23 and 32 frame is identical.
As well as the recoil spring/guide. As well as the magazines...all identical.
Drop in the 357 barrel, and have fun:biggrin:

if its a 2nd gen. 23....NO CAN DO

Sounds good= how do I tell what generation G23 I have?

[azdave12]

Most (typical) telling sign of 3rd gen. is fingergrooves......but most important is TWO pins holding in the locking block.....that is the design change which allows the frame to be used with either caliber.

The Glock 22/23 has had two pins holding the locking block in since first produced. In initial prototype trials agains the S&W 4006 for CHP the single pin G22 had a problem with the receiver stretching due to the faster cycle and higher pressures.
I have been punching out two pins since '94 on G22/23s.

Now thats intersting....the info I gave came right from Glock a few years ago! I called Glock CS before ordering a 32 barrel for my 23 from Glockmeister...just to make sure there wasn't any problems i was unaware of....what I stated above is what he said to me...plus he asked what my SN was, and supposedly "confirmed" it was good to go.
Not saying you're wrong, because I've grown to question alot of info from CSR's over the years....but what the Hell!


ETA some interesting info! Curiosity got the better of me, and of course late evening is not the time to call Glock with a ?:confused:

SO....I posed the question on Glocktalk....and the answer I get is that its a "more (thicker) steel reinforcement imbedded in the frame" thing .......'most' second gen. guns supposedly DON'T have it, and those SHOULD NOT be used with 357........ALL 3rd gen. guns DO have it.
The suggestion was to call and give the SN to have them check if 2nd gen......kinda what I did...even though I KNEW mine was a 3rd gen....and was given the strange explanation by the CSR.

[azdave12]

Call Glock Warranty Service at 1-770-432-1202 to run SN's on 2nd generation 23's.

Obviously, the CSR I talked to back then knew there was a SN data list with a cutoff SN to check for this question...he just didn't know the real reason for it...or confused it with something else going on with other models.


So...it appears "most" 2nd generations are a NO GO....all 3rds are fine:wink:

[Ssarge]

I'm not questioning the thickness of things or the cut off in SN's for .357 Sig ammo. I do know for a fact all G22/G23 have the two pins in the frame. I have been an armorer since '94 on the .40 Glock (been to Smyrna 3 times).

Uhhhh...I'm not questioning ANYTHING about the 2 pin issue--I'm AGREEING with you....I thought I explained it pretty well where the 2 pin issue came from.

BUT, thats pretty irrelevant...what IS relavent is that there IS concerns with 2nd generation 23's and dropping in a 357 barrel.....I stand correct in that assertion, just was misinformed as to the REASON for the asseretion.:wink:

And.....I was an LE armorer also.......but back in the days of "wheelguns"....seems like long, long ago.

If i need any Glock work...I'll send it your way...need a Smith re-timed, send it my way.:biggrin:

[Wadman]

But if you start out with a G31 and drop in a .40 barrel, you're good to go?

Hey - Ssarge!

I just bought my first-ever Glock. I decided to get the 17, and I was looking at two 17s side-by-side in the store. Both had light rails, and I think both had finger grooves. One had one pin, and the other had two. I bought the two-pin gun. Was the frame stretching and/or peening an issue in the 9mm guns?

Also - can I put a .40 S&W slide/barrel on this frame? The ejector on this gun is long and slightly bent/canted inward, as opposed to the shorter, straight ejector block on the 22 that I was looking at tonight.

Thanks for your help!

Peace.

I think Glock included the second pin on the 17s and 19s so that they had a common frame design with the 22 and 23.

[Ssarge]

Andy is correct. Glock just did it for ease of manufacture of the frames. (they used to call them receivers) It went into effect about a year into the manufacture of the 3d Gen. pistols, so some G19/17s have one pin, all newer production have two pins.
To make sure it's safe, I would talk to one of the tech's, not customer service about any mod's to the pistol. Of course even putting in a different barrel voids the warranty.

[brunop]

Thanks for the clarification. Now, one more question:

I understand that the peening problem is in the larger caliber pistols. Is the 'extended' barrel lock-up piece (sorry I don't know the right name) that my moderately knowledgeable (but not an Armorer...) buddy told me about, being done on frames besides on the .45 frames?

Thanks.

[armed1]

I talked to Glock today. Th guy checked the serial number and said its fine to shoot .357 through it. The warranty is not voided as long as I use a Glock barrel.
