View Full Version : G31 extended barrel

Someone posted a pic of a Storm Lake extended barrel for the G31 not too long ago. Just got back from the range, testing my new KKM barrel. It's a G35 357 Sig conversion barrel that dropped right into the G31 and performed perfectly.

150 rounds, GTG Ammo (100) and Underwood (50).

Never thought to do this with my G31..... looks pretty neat. where is POI versus POA?

Easiest way to put it is that the equipment is more accurate than the operator :) Good sight picture, good trigger control, it's dead on. And, that Underwood flying out the barrel feels like everything you imagine 357 Sig should be.

I have been really tempted to do this with my G23. I currently use it with a G32 barrel. However, I would love an extended barrel in it. It shouldn't cause any carry issues, but I would get G31 velocities. An extended barrel with ports would also be cool.

Here's mine.

Fits and works perfectly.

I use a 5" belly band that allows a custom fit similar to a shoulder holster or low-chest carry for driving or hiking underneath the vest I wear almost constantly. No carry problems whatsoever. Also have an IWB holster long enough to fit a full-size 1911 and the G31 with extended barrel fits quite comfortably.
