polymerfeelsweirdman Posted August 17, 2016 Share Posted August 17, 2016 I'm just wondering if anyone has tried this. I think it would be pretty cool. Also, anyone useit for hunting yet? Link to comment Share on other sites More sharing options...
Savagesweat Posted August 17, 2016 Share Posted August 17, 2016 I am saving up my allowance to get a G40 and when I do, I'll get a KKM conversion barrel to shoot 40 in limited. I have already done this with a G20 and it works very well, maybe the softest way to shoot 40 major due to the big frame and heavy slide, a much better option than the small frame guns, unless you have little girl hands.

DreGarciaTAT2 Posted August 17, 2016 Share Posted August 17, 2016 Although the g20 is a true 'large frame' Glock, the g40 is not... They changed a lot of the dimensions on the two 'large frame' practical/tactical glocks... Don't know if you knew that. For instance... Unlike the 20/21 and the 17/22... The 34/35 and 40/41 fit in the same holster. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Kevin G. Posted August 17, 2016 Share Posted August 17, 2016 OK, so I went to the Glock sight to check out tis G40 since I hadn't heard of it and see this pic... Can anyone explain what's going on with that pistol? Slide looks to be in full battery...Do they offer an extended barrel short slide gun? Link to comment Share on other sites More sharing options...
polymerfeelsweirdman Posted August 17, 2016 Author Share Posted August 17, 2016 Glock had sold the 10mm 6" barrel for years for the G20 I think the G40 still counts as a large frame Glock I mean the frames are the same and the slide is heavier than the G20 slide. The slide width might be different but I think the G40 barrel is the same as the G20 6" barrel though I may be wrong Link to comment Share on other sites More sharing options...
DLangan Posted August 25, 2016 Share Posted August 25, 2016 The G40 is a large frame. Frame size is the same as the G20, slide is actually .01 inches wider than the G20, then the 6" barrel of course. I haven't done so myself but I would guess that a 40 slide would fit on a 20. The G40 is essentially a stretched out 20. The G41 is a different animal however. Longer, narrower, and lighter slide. Definateley not interchangeable with a 21. However the frame, and grip size is essentially the same. Link to comment Share on other sites More sharing options...

Photo is of a G20 with 6" hunter barrel (factory Glock barrel), I have on in my safe and it works fine in my G20gen4. The G40 is a far better platform for that length barrel, as you get the advantage of a longer sight radius. ~g Link to comment Share on other sites More sharing options...
target4fun Posted September 2, 2016 Share Posted September 2, 2016 I am probably wrong, please let me know. Isnt the G40 a 6 inch barrel? Thus being to long for USPSA limited? I have the G20 but like a 2nd gen model, I have been very interested in the G40 since it came out as I love the 10mm round. Also as far as barrel upgrade goes would you be looking at a barrel upgrade for accuracy or fully supported chamber only or both? Just curious if yall see a difference in accuracy with upgraded barrels or is it just for the supported chamber. Thanks Link to comment Share on other sites More sharing options...

Thanks Glock 24 is 6" too and is legal barrel would be more to have it chambered for .40 S&W Link to comment Share on other sites More sharing options...

Peterock Posted December 22, 2016 Share Posted December 22, 2016 I just acquired a brand new .40 MOS and now I'm in a quandary of what to use it for. Drop a ,40 barrel. Mag well, (slide lightened?) trigger, maybe Arredondo mag extensions ? if I run .40 in this platform do I simply use the 10mm mags with .40s? Do I need to load them long?

Peterock Posted December 22, 2016 Share Posted December 22, 2016 I thought it would make a hell of bowling pin gun with my RMR mounted. Link to comment Share on other sites More sharing options...
polymerfeelsweirdman Posted December 23, 2016 Author Share Posted December 23, 2016 I never got around to doing this with a G20 or G40 but this was my parts list I had in mind (and this would apply to both): KKM .40 barrel Carver magwell or Suarez magwell - these are basically the two I found that worked for the Gen 4 large frame guns, with the Suarez being a carry magwell but allowing regular mag use; a compromise but I had this idea of having the gun pull double duty for competition and hiking/hunting/whatever Liberal use of grip tape Connector kit (TTI, Ghost, etc.) Dawson sights - would probably lean towards an adjustable rear since there is so much variability possible in .40/10mm loads but this would be a trade off for the G40 because it would prevent you from using an optic without removing the sight TTI large frame mag basepads - listed as for the .45 acp Glocks but should fit the 10mm ones Stainless guide rod & reduced weight recoil spring - I would consider giving the stock dual spring setup a try first since they seem to work reasonably well for a wide range of 10mm loads but ideally this would be done Maybe: Extended slide release - I don't think I actually need it Extended mag release - possibly if I found one I liked, could also try an epoxy build up on an OEM one Flashlight weight - haven't tried it but seems like fun; I'd be compelled to use steel shot so as to not completely lead out a flashlight I'd probably end up reassembling at some point and the gun would be fairly heavy already from the slide Link to comment Share on other sites More sharing options...
Peterock Posted December 23, 2016 Share Posted December 23, 2016 I like where your head is at, this is a very similar build to what I was thinking. I'm thinking a heavier magwell and brass plug though to help get some weight under the gun. It's already somewhat front heavy. I was thinking an SJC frame weight and thumb rest, Dawson Brass Magwell with heavy insert. Rear sight is an issue since I do plan to run my RMR when not using for comp, but most options I've seen that work would have to be fixed rear. Is there a way to make the factory adjustable better/more precise? Link to comment Share on other sites More sharing options...
