Sooo, it seems the 357 sig has garnered some attention again. I’ve read several comments about a desire for a 357L, or something longer than the 31.

Comments on why this has not happened and/or will it happen with the generation 5 product?

I wonder if Glock supports this cartridge to its potential? Your comments would be appreciated.

Now that I think about it, search for a G24 length aftermarket barrel?

Forget Glock, it's just not going to happen, but I am sure someone either makes or CAN make a .357 auto barrel in the G17L / G24 length? For the right price.......................... :(

BTW, isn't the .357 auto designed around a 125gr bullet from a specific length barrel also? I'm going to guess a 4" barrel or so? Maybe whatever either a Sig P229 or P226 barrel length was? I mean as far as what the round was design to be most effective with bullet weight and velocity wise?

Given the limited amount of possible bullet weights available in the caliber, you may get into a situation where pushing the round does not necessarily improve it's performance also?

I don't know I'm just guessing here, knowing that with some other calibers you can reach a point where pushing them velocity wise does not necessarily improve their performance also? :( Again, I could be wrong too, someone please correct me if I'm wrong?

I have been watching for another G-24, I had one and had to let it go. I had the same idea of getting a 357 barrel for it.
I have been thinking about building a 45 long slide also. I have been told that Lone Wolf has a Barrel, and slide for a G-21 slide. I have a G-17L, and would like to set up a few more.
I had a slide, and 6" barrel on a 1911 frame at one time.
I like long slides to shoot at the range.

I've had both a 357 Sig conversion barrel for a G35 in a G31 and a G35 converted to 357 Sig with a Lone Wolf barrel, my chronograph results with my hand loads show a increase in velocity with the same load though I don't believe it was an "apples to apples" comparison due to polygonal/conventional rifling differences between the stock G31 barrel and the Lone Wolf G35 conversion barrel.

check out the link below for a more in-depth barrel length/velocity comparison.

Question -

You guys shooting .357 auto (let's say out of a G31 sized gun - a full size, at least 4" barreled gun?) how do you find it compares to shooting .40?

Louder? More recoil? More blast? or about the same, or less?


How about vs non- +P .45 or non-"nuclear" (factory) 10mm loads?


Thanks -

The sig using light bullets has the best combination of power generated for the recoil in my opinion. Now granted i was using a large gun (g21 longslide with 6" g20 sig barrel) i made over 800lbs of energy with the sig and 125gr bullets loaded to 10mm OAL length. These were over 1700fps and recoil was soft and easy to control. It was softer than my 45 loaded with 230s at 1100fps (617lbs).

The sig is a loud round however, especially loaded hot with slower powders but its recoil is much softer than what its power suggests it should be especially with light bullets. Ive gone up to 180gr bullets with the sig and then its recoil starts matching up favorably with the 10mm and 40 rounds given equal velocity.

So what do you think the reason is for Glock NOT supporting the 357 sig in something longer than a 31?
Actually, my retort was reference the 45 GAP comment. To answer your question, every decision Glock makes is simple = Money. They must not think they can make enough selling them. Maybe since its another gun manufacturer's round like the 45 GAP? Although my anecdotal observation of the round does seem it is treated somewhat like the 45 GAP, the bottom line is you gotta bring in big money at the small, medium and large shop before you get dressed out as a race car. I don't think the GAP or 357 Sig will ever get there.

Every year I hope for a new model in the Glock 357sig lineup of either a prac/tact length or long slide... and every time it's a new 9mm. :faint:


I like 357sig, and I like long slides and long barrels too!

The G40 with 357sig feels like your shooting. 380.

I made it past the contemplating stage, Gen 3 G35 with a KKM 357 Sig barrel. The only thing I regret is that there was also a G24 available AND KKM makes a 357 barrel for that as well!
I bought a 24 for the purpose of 357 sig. I used a 6" KKM barrel and it was very accurate. It sounded different than my 32 I had to compare it to. Not sure if it was distance of muzzle or that it burned more powder and was more efficient with less 'flash'. Anyway, between the weight of the 24 slide and the extra weight of the 357 over the 40 barrel - I didn't like the weight distribution amd how it handled. I sold it and my 34 at the same time planning to get a 35 but something else caught my eye. I never forgot about it and would get one today if I was a true pimp. I think the 35 is perfect for it. You can get a threaded 357 barrel for the 35 if you want to ring out all you can. You could use a 6.5" threaded barrel for the 24 and LWD even had 9" barrels a while back.

The Long Slide G17L (1988) and G24 (1994) with 6.0-inch barrels filled the niche for a gaming gun rather than that of a weapon for common service issue. However, their size disqualified them from some competitive uses, so along came the Competition-sized G34 (1998) and G35 (1998) with 5.3-inch barrels.

The Competition-sized G41 (2014) with 5.3-inch barrel and the Long Slide G40 (2015) with 6.0-inch barrel appeared more than 16 years after the G34/G35. The G41 seems pointed to gaming, and the G40 to hunting. During the first 30 years of Glock history, nobody interpreted the absense of OEM pistols with barrels longer than 4.5-inch as a sign of Glock's wavering and uncertain support of 45ACP and 10mm.

Similarly, the lack of such models in 357SIG means nothing. There are Subcompact, Compact, and Standard-size 357SIG models available in both Gen3 and Gen4. In the absense of great interest in 357SIG for gaming or hunting, it is not likely we'll see OEM models with barrels longer than 4.5 inches. It would take Glock perceiving a profitable market. (It's a shame, because it would require very little effort for Glock to make a 5.3-inch 357SIG model.)

But... with 45GAP we see what company uncertainty looks like. The G38 and G39 have never been made in Gen4 versions. The 45GAP models use the smaller narrower frame of 9mm Glocks, and then that size advantage is wasted with a slide the same width as a G21. That's an amazing design error, because the earlier G36 with its 1.0-inch wide slide had already shown how easy it would have been to produce 45GAP models that were size identical to 9mm models. That was the only path to 45GAP commercial success... and that path wasn't taken.

Do you see a wrong for those that have posted here; their fix to get that longer model they desire?

In case anyone was wondering, a G24 barrel will drop into a G35 with no problems.

Barrel is a Lone Wolf G24 .357 Sig.

:thumbsup:
I had this exact set up with the barrel cut and threaded to match the slide length. Then, I had to sell it. I now have a second G35 with the threaded AW barrel. That set up produces less muzzle flip (using relaxed grip) than my G41.

I find the 22 with more push than the other two calibers.
Agreed, in a way. My 35 with the OEM barrel feels like it 'thunks' in your hand more than the Sig barrel does, using plinking ammo with each. It's not a big diff, but it's there.

.357 Sig is popular enough, now, that Glock should consider a 6" slide version. You could probably get 1600 fps with some good ammo, out of one, which would make a good trail gun...without the recoil and percussion of a 10mm.

Forgot to mention even though it isn't a 'true' .357 Sig pistol, my AW threaded barrel is just a tic over 5.8". I have a thread protector on it (always have liked that look) and the package 'just works'. Bad thing is you have to buy the 40 cal gun and a barrel, but you could hunt down a used one and with the barrel, maybe be at a price less than a long slide .357 would cost you. Glock ain't giving away the LS 10mm...they sure as hell ain't gonna give the LS, .357 Sig pistol away.
With the 10mm you can have three guns in one with a 357 Sig conversion barrel.

I would suggest a G35 w/6" KKM barrel or a G24 with same bbl. You can get some good numbers out of it, but I would say it's unlikely for Glock to introduce any new 357 SIG guns. Yeah they may do a Gen5 version of the G33/32/31 but I doubt they'll ever release a new model in 357 SIG. They've had plenty of time to come out with a 34/35 sized 357 SIG but haven't, and maybe I live under a rock, but I don't see where it's gaining any ground in popularity, even though it does deserve to be more popular.

I believe the education from Grt45, Happietoshoot, and many other posters through these threads and others has shown myself and others what can be done.

Although Glock may not produce what you desire you can either...... pout and complain or participate in the aftermarket of what ifs..because it probably can be done.
