niroth81 Posted May 11, 2018 Share Posted May 11, 2018 I have a PT Evo grip on the way for my open gun. I've heard that they are pretty much a straight fit up. How do you check for a good grip to frame fit? What would need to be adjusted and where if it doesn't fit up 100% from the box? Link to comment Share on other sites More sharing options...
echotango Posted May 11, 2018 Share Posted May 11, 2018 Mine were nowhere near a straight fit. My first one took me a couple hours and the second one took me an hour. Perhaps if you have a PT frame that go right on. Patience is your friend while fitting. Link to comment Share on other sites More sharing options...
Acsr Posted May 11, 2018 Share Posted May 11, 2018 Quite a bit of sanding/ fitting on mine which is a sti frame my advice take it slow because you can't put material back, mine is a snug fit and no play but I don't need a mallet to install. Good luck and go slow Link to comment Share on other sites More sharing options...
niroth81 Posted May 11, 2018 Author Share Posted May 11, 2018 Where is the material that needs to be removed? The grip I have currently needs a bit of upwards pressure on the trigger guard screw to get on there but not excessive. Should all the holes line up perfectly with the PT to be a good fit? Love to see some pictures if anyone has them? Link to comment Share on other sites More sharing options...
teros135 Posted May 11, 2018 Share Posted May 11, 2018 PT told me it is designed to be a slight interference fit, about .001". You may have to tap it lightly with a mallet to set it fully. It fits well with on PT frames (my frame was two years older than the grip, and it fit perfectly). Other frames have more variance, depending on how many frame suppliers they use. Fit is more critical with steel grips. My (older) STI frame is .008 too wide; my CK frame (2014) was .006 too wide. I'd use a gunsmith to machine it if it's more than .003 off, to get the sides flat and parallel. Link to comment Share on other sites More sharing options...

Then if you make a mistake, you can still put your original grip back on and go shooting. Link to comment Share on other sites More sharing options...

I'd rather shave the frame, so the grip could be used on another gun later. YMMV. Also, if you shave the frame .006, I'm guessing you could easily attach a plastic grip later (for instance to sell the gun) because they flex.

SDL Posted May 11, 2018 Share Posted May 11, 2018 I was told if you don't fit them well and force the grip on it can distort the slide. Link to comment Share on other sites More sharing options...
Knguyen1904 Posted May 13, 2018 Share Posted May 13, 2018 I was worried about the task of fitting the pt evo as well as the sv infinity model so I went with the ck arms model . Slid right on to my sti frame applied a little loctite to the appropriate screws and has been solid for a couple thousand rounds. No regrets .

Cosmo71 Posted May 28, 2018 Share Posted May 28, 2018 Fitting my PT Evo grip to my Edge took me 3-4 hours using Dykem, flat files and dial caliper. I was in no hurry, enjoyed the project and ended with a very nice tight fit. Only took material off the grip and as others have stated above, have patience, you can't put it back on . Color the inside surface, test fit, file where it's shiny and repeat and repeat and repeat...…. Link to comment Share on other sites More sharing options...
Gunz720 Posted July 8, 2018 Share Posted July 8, 2018 Mine took a lot of fitting for my DVC but love the grip Link to comment Share on other sites More sharing options...
Nalle2491 Posted July 24, 2018 Share Posted July 24, 2018 (edited) I have a pt evo on my ck hardcore and there was almost no fitting required. It was amazing. Also, it comes with its matching beaver tail and that piece is pretty much a drop in part. Can’t ask for anything better.

MedicAJ Posted November 29, 2018 Share Posted November 29, 2018 I just received my PT EVO grip last week. It went onto my STI frame (TG prefix, DLC coated) without any fitting needed, however the fit was so snug, that it was pinching the frame enough to prevent the slide from moving on the frame rails. Will take a touch of fitting to fix. Andy Link to comment Share on other sites More sharing options...
ACree Posted November 29, 2018 Share Posted November 29, 2018 Mark the frame, try to seat the grip, file or stone, refit, rinse and repeat. A rotary tool can help as well as long as you are careful and don't make a mess of it. Link to comment Share on other sites More sharing options...
4thquarter Posted December 3, 2018 Share Posted December 3, 2018 Slow and steady, mark the fitting pads with a blue marker, dry fit then stone/file repeat..... Link to comment Share on other sites More sharing options...
