Yes. 6" KKM 357 Sig barrel in a Glock 35.

Flame? No, but my carry ammo is Underwood which uses flash suppressant. Though I have not noticed flash in any of the training ammo I've used.

My intent with this gun was to create a flat shooting long-range pistol. At first it didn't work well for me, the recoil wasn't bad but the muzzle flip was intense. I simply wasn't getting the accuracy I wanted out of it. I asked Yondering to make me a compensator for it...and that made all the difference. The 115 gr Underwood comes out of there at almost 1700 FPS...which is interesting I suppose but what really matters to me is that it shoots very flat and it hits with a lot of authority even at 100+ yards. It is very accurate; I can basically hit whatever I want with this pistol even without the PDW brace.

It is rather a lot to carry AIWB. I have done so and it's no big deal, but it's not my favorite to wear in a holster. For my purposes it worked out really well turning it into a PDW.

The comp does make it really loud, and depending on your shooting position you will feel the blast (such as on your back, shooting between your knees). I haven't tried removing the comp while shooting with the brace, and will probably leave the comp on there until the tax stamps go through.

Brent, is there any difference between POA and POI at 100 yards?

I'm sure there is but I haven't measured it on paper. At that distance I've only shot steel.

Last time I was in Prescott, I took aim at a 12"x12" plate (maybe a bit smaller but I don't want to overstate). The farthest I could shoot safely, with students around and such, was 109 yards. I sat against Gabe's truck, braced the pistol against my legs (I didn't have the PDW set up on it at that time). I took aim at the center of the plate. Ding ding ding, three in a row. I couldn't see where it hit, I just know it hit. POI couldn't have shifted more than 6" and I'd bet it was less than that.

Thanks ,I had not considered the 357 Sig.I am now.What manner of folding device do you have on your PDW. Doug

That's a great set-up, Brent. I love .357 Sig, it's my EDC in a Glock 32. Would love to put a RDS on it in the future.

Out of destruction rises opportunity. Never, ever give up.

That is an MDTAC. More expensive and heavier duty than necessary for this application but I'm an overkill kind of guy. I'm sure with more research a more reasonable but solid option could be found.

G35 6" with comp and folder compared to a G19 and no folder. Both are good set ups and for similar roles, one has more thump at range but the other is lighter and so small.

Thank you very much,for the info.Much appreciated.Doug

A folder on a Glock PDW, very nice. Might have to try that.

A folder isn't for everyone but it suits my purpose well.

How do you get a G19 to fit on an ENDO ?

How do you get a G19 to fit on an ENDO ?

It requires drilling a second hole in the Endo for the pin, and grinding some clearance for the magazine. The G19 in Brent's pic is mine, and is a gen4 so it also required whittling down the prong to fit in the smaller grip recess. Not a big deal to do, pretty easy if you have access to a belt grinder.

I think Brent wanted to see the gun. I know I do.

Just a standard black glock 20 sf with a 9 inch barrel regular glock iron sights. Nothing fancy right now
