X5 Leginon grip modification idea and carry Optics Legality

Recommended Posts

Hey All,

 

So I picked up an X5 Legion to give carry optics. So far I have been pretty happy with it, and I love the weight of it, but I found the grip dug into the the base of my thumb, which drove me nuts. I realized that all of my favorite guns have wide grips with narrow beaver tails, Tanfo, CZ, 2011. I was afraid to start cutting on the fancy legion grip, so I used part of my $200 rebate to get a standard polymer X5 grip, to modify. The modification was a little rough, because I rushed a bit, but I think it feels 100 times better now. I also realized that Sig does offer a similar narrow beavertail grip the for the XCompact, but its grip diameter is smaller and it doesn't have the same magwell, which we need for competition. Don't even think it would work with the 5" barrel anyway, but I handled one at a local gun shop, and it similarly feels way better than the standard X grips.

 

Question is, would this grip modification be legal for Carry Optics (or Production)? I want to be sure before modifying my actual X5 Legion grip in the same way.

It’s legal. I did the same thing on my old X5 grip and just did it on my brand new tungsten grip module. I used a dremel with sanding drum progressively sanding it until it was smooth.

Looks like I kind of reinvented the wheel a little bit, but I did execute the modification a little different that the others on your topic. Also, it has been verified it is acceptable for carry optics, but if I took the optic off and wanted to go back to production, would it still be allowed?

 

Side note, does anyone know the optimal FPS / IPS cutting speed for polymer, or the tungsten polymer? I am actually using an end mill on my drill press with an X Y vise, not sure if I was cutting at the right speed...

Don’t sweat the mag well. It’s not legal in carry optics. And all grips, slides, and FCUs are interchangeable.

I was talking about the polymer mag well in the grip not the detachable one.  Notice the different curvature of the rear of the grip near the bottom too.

I worked up the nerve to make these modifications on my Legion Tungsten grip. I think the results came out really well, photos to follow...

Pic of my "milling" set up. X-Y vise, and a cheap craftsman drill press. Actually worked quite well for this.

In case anyone cares, my modification removed 0.14 oz from my tungsten grip module.

Nice job! The first work I did on mine was dremal the edge off. Made my thumb hurt so much.

I read somewhere that it was to break up the gun visually and make the bore axis appear lower... Could be wrong though...
