P245 magazines
Are the Promag offerings any good in this gun?

S-I-L is looking for a couple,for the P245 I sold him a few months back and of course Sig has discontinued them.

I don't think you'll find anybody recommending Pro-Mags here. My experience with one was poor. But that was a long time ago. You might be surprised and get at least one that actually works. Check the seller's return policy, and relegate them to target/range practice.

Possible alternative: Armscor/ACT-Mags for P245 & P220 Compact, 8 round with finger extension from Greg Cote Like all extended mags, this kind of defeats the purpose of the short grip for carry.

I have NO experience w/ Promags, but if I'm a betting man, probably NOT.

That said, there are other options you may or may not be aware of:

- P220c mags are basically the same w/ a slightly different profile to the baseplate estension.

- P220 mags work just fine, though obviously NOT ideal for concealed carry. The do make great spare mags/reloads for CCW though.

- X-Grip Mag Adapters used w/ an 8rd P220 Mag are a great option and essentially create a DIY home-spun P220 Carry. I have a few and use them for range use, which honestly is the only use my P245 gets anyway.

Available from GregCote LLC @ $15.95 --> https://gregcotellc.com/cart/x...cp-xgs220-p-972.html

Here's a pic of my 'KK' proofed P245 w/ the X-Grip:

Yes, factory P245 mags have become hard to find and are ruinously expensive when you do. Personally I wouldn't even buy a promag to use as a training mag. I do currently have one from a Compact P320 that somebody gave me for free and I have been playing around with it to see if I can get it to fail. So far it hasn't, for what that's worth, but the quality control is visibly inferior to my Sig mags.

For the P245, if she's got a couple of factory mags she could buy some full-size P220 mags to carry as reloads, and carry the shorter mag in the gun. That's what I did when I carried my P245, and they worked great and you get 2 extra rounds. Full-size P220 mags are still readily available and reasonably affordable. The ACT-MAG aftermarket ones that Greg Cote sells are just fine, too.

I had trouble with a P229 magazine a while back, at an OpSpec Training event. Bruce Gray got one look at it, grinned, asked, “may I?” and tossed it into a trash can. Then he grinned again and said, “friends don’t let friends run ProMag.”
