Advice on cutting down a P250 frame
I like the size of the P250SC but prefer the grip length of the compact.

If I were to attempt to cut down the frame of the compact to the length of the SC slide what tools would be best for cutting the polymer?

Would a circular saw work ok and then file the edges down a bit?

Has anyone done this already? Any pics?

Thanks

I’ve chopped the grip of a few frames using a Dremel cutoff wheel. Slower than normal speed so the plastic cuts rather than melts took some practice. Just plan your cuts to leave room for sanding for final length/shape. Some painters tape as a guide was helpful too.

I shortend a P320 compact frame to fit my subcompact slide by using a fine tooth hobby saw (Zona). If the P250 frame is similar, you will get a larger gap at the muzzle end, however, the only person to see it is the bad guy. It worked but never looked unmodified (frames don't cost much).

A coping saw with a fine tooth blade will also work. Clamp the frame in some sort of vise, if you have one.

Cut the frame very slightly longer than you want the final result. You can use sandpaper to bevel and smooth the edges.

If you follow up with some very fine wet-or-dry sandpaper, you can get a very smooth result.

Buy a P250 380. The 380 came in 2 versions, 1 with a subcompact frame & 1 with a factory cut down frame to fit the subcompact slide. You get a frame & a 380 to play with.

The muzzle end of your modified P250 frame is substantially the same as a factory-modified 380 Compact frame. The biggest surprise to me was that the gap between the modified frame and slide is not tremendously larger than the gap between an unmodified frame and slide.

Thanks for the pics Gary. That is good to know.

Might be off-topic a bit, but you can get close to the same result using Compact magazines with X-grip extenders in your Subcompact.

I used a cutoff wheel on a dremel. Then sanded with scotch brite pad. Cut long and sand to proper length would be my only advice. Don't overthink the cutting part, its plastic.

Thanks Toivo!

OK, also chopped down the compact frame. Not quite as nice as Gary’s but it will get the job done.

Thanks guys!
