Shortening the grip on a Glock

Who has cut the grip of a Glock to the next size down? Specifically, I want to cut a G20 grip to a G29 size.

Any advise is much appreciated.
 
Just trade the 20 for a 29 since you want to cut down a 20 to the 29 size.

+1.
I've read somewhere that the velocity loss is only about 60fps. Otherwise, Robar does the chop job too.
Has anyone tried chronoing these two side by side?
 
I want the advantages of the G20 (longer sight radius, increased velocity, ability to use 6" barrels) with the advantages of the G29 (shorter, more concealable grip). I carry IWB, so the longer slide length does not matter.

I do not WANT a G29.

I do NOT want to turn this into debate over whether cutting a Glock frame is a desirable modification.

I am looking for insight and advise from those that have done this. I have searched here and at glocktalk.com and have not found much, though I know people have done this.

Thanks for the leads Stevelyn and Longbow. This appears to be fairly easy to do and I would like to try it myself.
 
When I get some time I am going to puzzle on one of my G17s and see if it is viable to cut the grip to G26 dimensions, ought to be quite the concealed piece being that a full size slide is easy to conceal, the grip is the hard part.
 
Kilgor, I've seen pics of this conversion and some explanation of how it was done. I'm pretty sure it was at glocktalk. Keep searching.
 
I take NO responsibility for your actions, this is merely my experience.

It’s really quite simple if you have the tools or at least access to them. I’ve chopped a G17 to a G19 and another G17 to a G26. While I suppose you could measure off of a magazine to do it, find a friend with the appropriate size smaller Glock and use his frame to scribe a template line on your own larger. I suggest fieldstripping both pistols, taking the pins out of the lower receiver of one and drifting the pins halfway out of the other. Mate the two frames using the half-in/half-out pins and scribe the line.

The frame cuts quite easily with a pocketknife, so do a rough cut like that. Then fully assemble your pistol (slide and all) and use a vertical mill to finish the cut to your scribed line. I ran a 1/2” end mill at about 2000 rpm and it cut very nicely.

Two things to keep in mind are the contour of the backstrap and the bevel of the magwell. You may want or need additional work on the backstrap to make it more comfortable, mine are just fine for me. Also, beveling the magwell is always a good idea, but will be necessary on the G19 size grip if you want to use the older NFML mags with the tapered baseplate. If you only have the newer mags you don’t HAVE to do it, but I would suggest it just so you can pick up any caliber appropriate mags and know they will work. I’ll take some pictures and post them if folks are interested.

Some may ask, “Why?” I’ve never liked the G17 grip, the backstrap curves at the wrong place for me and it’s just plain HUGE!!! The G19 grip is almost perfect for me, so I started there. Then I found a cheap 2nd Gen G17 and was thinking the same as Nave Joe. Longer barrel, sight radius, cheaper recoil springs, etc., so it became became my G1726. It is exactly what I want it to be, though I did have to fashion a “lip” at the bottom of the frame where the finger grooves normally are on a G26. That little lip keeps your finger from getting pinched on mag changes with the G26 mini-mags.
 
I like your idea of a 20 slide with the the 29 grip length configuration. I considered doing this myself when the ban was in effect. Now my projects have drifted in other directions, but I still think this would have been sweet.

If you do it be sure to post the obligatory pics.

It seems to me that a 20 mag could be fitted with an extension above the floorplate which would mimic the lower portion of the grip frame of the 20.

This would give you the benefits of both mag lengths, though spare mags would be cumbersome, unless you limited your spares to 10 rounders.

Anyway, I think it is a nice idea.
