Ok.. need some breaking in.

I got these for the M18. They dont glide in and out like original sig mags. They will need a break in period. Also, they will not fit in the Wilson combat grip unless you shave down the base plate ears a bit like the original sig mags do. These base plate ears are squared while the originals are tapered. They do fit the original grip module for the m18. So I cant complain about that aspect. Lets be real though. Who is still using the original grip and not the Wilson combat when its only 65 bucks??? If you taper those little wings/ ears on the base plate so they fit the Wilson combat grip you would have a perfect product..

If you don't want to pay for Sig magazin

definitely not a factory Sig Saur magazine. Can tell it is not as durable immediately. You get what you pay for.

Great finish

Great finish, little hard to load, no issue it all when use firearm

Get what you pay for

I got 3 mags to use on my sig p320 full size stock grip. The little wings at the base of the mag need to be shaved down to even fit. Spent 30 minutes with a file and still is very snug. Mag release is hard to push because it's still so tight. Guess I will need to get my grinder out so I can use my brand new mags. Kinda dumb. Will wait for sig mags to be back in stock next time.

Trash Mags

Doesn’t fit AXG Legion or metal grip modules. Performs terrible on X-Compact. Trash mags!!!

Not for

I got some of these ProMag P320 17rd magazines to try since they were on sale for $15. The body of the magazines seems fine, it has a finish that has a good grip, but might have drop issues when empty. The guts and base are cheap. The base plate insert is very flimsy and doesn’t align the base plate well. I have extra base plates and inserts so that is fine for me, but not everyone will have spares. I had to put in mag blocks so that helps stabilize the cheap spring. The follower is flimsy and might lead to feed issues. It was worth buying a few to try and have for the range, but I would not recommend them, nor use them for carry or competition. You get what you pay for.

Cheap junk

All sorts of issues. Spring is miss shaped so the follower doesnt ride right at all cause several issues. They dont drop free when empty. Will only run reliably with 15 rounds not the full 17. Cheap Chinese range mags after an hour of work each mag. DO NOT USE THESE FOR ANY DUTY/CARRY OR OTHERWISE PROTECTIVE PURPOSES.

Sig 17rnd Pro Mag magazine

The magazine would not activate slide lock lever with empty magazine. Stretching the spring was not a fix. I had to replace the spring with a Sig Sauer 13-coil OEM spring for full function.

Absolute garbage

Got three for Christmas, all three have issues where the followers will tilt and allow rounds to rattle around inside the mag and when empty pop out if the top. This is without ever even using them, just loading for the first time.
