Would not recommend
The part of the plastic base that meets the magazine well is to thick to go in the magazine well without having to force them in. Once on the magazine is very hard to remove because of the plastic base

Ahhhhh Noooo
First and last time buying a ProMag, clip fell out when firing, jams up when it gets to like 8/7 rounds and couldn’t fit the last round in mag. Here a rattle inside the mag after loading.. I’ll stick with stock Sig or ETS for now on

If you want a single-shot semi-auto...
I had two different issues - either the slide would lock back, or the trigger would fail to reset. Great way to turn a semi-auto pistol into a single-shot, but not useful for my purposes. Why didn't I trust other reviews? If you do risk the purchase, save all of your packaging, and go ahead and request a return label when you place the order.

Stay away from it.
I should follow advise of the fellow buyers, who gave one star rating to the product. I got two magazines. Being an amateur gunsmith I was absolutely sure, I will be able to modify magazines in order to reasonably useful. By visual comparing to the original magazine I noticed the difference in the upper opening. The lips are longer, positioned closer and have rough edges, which makes inserting rounds rounds very hard. the rear edge of magazine have very narrow cut, much narrower than original. Internally magazines are different as well. The spring is about 1/4 thicker and harder. The follower have a long skirt and different shape. Practically it is not possible to load more than 10 rounds. I am wondering. How it is possible to sell a product, which supposedly be an adequate copy of original and be capable to replace original product, but obviously is a junk? Using a Dremmel tool a made all necessary cuts and modifications as close as possible to the original. I am able to load 17 rounds with some difficulty. Using the Glock type magazine loader makes it much easier. On the positive note, I purchased ProMag products in the past and it is a first time I encountered such a difficulty.

Probably Not
ProMag has not failed me in the past since their AK-47 Mags are the ones I recommend to a my friends. I Bought 4 of these and thinking they would have the same quality, but trying to fill these mags past 13 rounds is a chore and shooting with more then 13 would keep my slide locked open after every shot until I got 4 shots out. Its also worth noting that my P320 has a Hard time fitting these magazines like the gun is saying "Please don't put these Magazines in me." For now stay away, who knows maybe ProMag will fix it in due time. Until then just buy factory.

Okay for plinking
Okay mags for range use. They are not reliable other for hard use. If you are looking for self defense purposes spend the money on factory mags.

Terrible Magazine
Won't feed properly. Not compatible with Sig 320.

I wanted to give this a 0...
I don't often take the time to write reviews. This is about the worst product I've ever bought. (I bought 2) I have a Sig P250, (if you look at Sig's site, the 320 and 250 share the same magazines. -I could (by hand) not load more than 11 rounds in to one of them and I got 12 into the other. -Rounds wouldn't slide forward smoothly even when just using my thumb to unload. There was an overly acute bend on the retention lip. -worst of all; it stopped the slide from moving forward into battery. This product was 100% useless. I could not get it to load a round into the chamber of the firearm unless I released the slide release, and then hit the mag release and allowed the mag to slide down and get out of the way of the slide.

I would never purchase another promag product again
This is possibly the worst manufacture of magazines in existence. First I opened the package, inserted it empty into my Sig p320 and noticed right away resistance sliding in. I mean not just from friction, but actual physical resistance from the magazine rubbing hard against the mag well and mag release button. Needless to say when pressing the release button the mag did not fall free. I had to use force to remove it. Upon inspection, and comparing the promag and a factory mag from Sig, there are some distinct differences, mostly the cut out for the release button is not cut on an angle like the Sig mag, and one edge of the mag is not as rounded as the factory mag. Stay far, far away from this manufacturer.

will this fit the m17?
Answer:
Yes it will.
Will this work in a p250?
Answer:
Yes it will.
Have the problems with the P320 compact magazine been resolved, as the comments here are rather old? Also, you mentioned a replacement # MAG-467-032, but it is not on your web site.
Answer:
While aftermarket magazines do save you money they are not always as reliable as the OEM magazines. If you would like factory magazines you can use item 2-MGSGMAG-MOD-C-9-15
