Works Fine for Me
I was pleased that the 2 mags I ordered came with the sleeves as well. I've only ran 1 mag through each in 2 different LCPs and had no problems with malfunctions or with the mag locking into the pistol. I've had good experiences with every Promag product I've used. I'm back ordering another for my father in law for Father's day.
Good product, reasonable pricing.
Bought two for practicing PPC on the range. No jams, no malfunctions-worked perfectly.
Non functional
I purchased one as a backup. It did not engage the mag release. I returned it to pro mag for a replacement. The replacement also does not function. I believe it is an inferior product.
Doesn't seat or feed properly
Picked up two of these for range days. Neither one seats properly or feeds properly. Can't even rack the slide on the off chance I get it to snap in. Sometimes too good to be true is actually that. Half the price = half the quality. Will order new mags directly from Ruger. Thankfully Brownells makes returns easy.
Not Happy
I have Ruger LCP 380 1.25" Extra Long GARRISON Grip Extensions (2 of them). One fits precisely right on the stock magazine that came with the Ruger. There is a button on all 380 Magazines spring plates that fits into a hole on the magazine end plate, which is what the Grip Extensions are. The button on ProMag magazines appears to be offset and will not line up with the hole in the Grip Extensions. So, the Grip Extensions will just slide off. Not happy!!! Would not recommend!!! I threw all of the packaging out already, so I can't return. Frankly, Iin forget where I just bought them from too. Oh-almost forgot, the magazines with the Grip Extensions won't click into place in the gun. They just slide out.
Don't waste your money.
I bought 2 of the pro mag 6rnd mags for my lcp to practice reloads at the range. They failed to perform the first time out. The follower gets stuck down in the mag on the catch when loading and unloading. The follower is a flimsy piece of junk. It's hard to mess up a single stack magazine but pro mag has done it. If they would improve the follower quality then perhaps the mags would work better. But until then I won't be purchasing anymore products from them.
