The MM frame is a CHUNKY monkey dude.
I have the Omega with full length dust cover and grip panels.
Was Steyr the original modular gun concept manufacturer who never sold any frames so you could, uh, modulate???
And at some point I need shoot a P365, like the new comped version.
I finally was able to get to the range and shoot my P365. It has the Boresight Solutions Razorback grip module. I've read statements that the P365 is accurate, but it's usually people who shoot a lot. I dry fire occasionally(with my G19 and J frame) but haven't been to the range in over a year. Anyways, I was impressed with the P365; left-handed, right-handed, and both hands made tight groups(for me). If I was a better shooter I think I would have had one ragged hole. I assume the Boresight grip and the inherent accuracy of the P365 did all the work. I was thinking of selling it and buying a G34.5 but after shooting it, I don't know. I don't carry it but maybe I need to start, but I've always wanted a G34. Now the Kel-tec P32 and S&W 43c are a different story.

The most popular & successful modular weapon to date is the AR-15 (M-16, M-4 Carbine etc.) that was first designed in the 1950's by Eugene Stoner and associates. Stoner tried to develop the modular concept further in the 1960's with the Stoner 63 weapons system that saw some use by special forces in the 60's and 70's but never really took off.
For a modular system to work the parts need to be truly "interchangeable' and not just marketing BS.
I think SIG has hit on a winner with the P365 system. The merchandising of the P365 with different barrel & slide lengths, magazine capacities and grip ergonomics is pure marketing genius.
