Ratings and Reviews of +3 Magazine Extension for Smith and Wesson Sigma & SD and SD 2.0 9mm Pistols

I bought one of these mag extensions for my SD9 2.0 and I am very happy with it. It re-uses the factory mag spring, and was easy to install. I fired it full, three times and had no issues. The slide locked back on empty. Feels solid and well built. Would recommend.

I ordered the +3 because it does give a little more grip for the pinky, never hurts to have a few extra rounds, and is still easy to CC. Fast delivery, maybe 3 days. Went to the range today and had no issues. Ran FMJ, Federal HST, and Critical Duty through it with no failures.

Bought one to “try”. This pistol always seamed small and little to light in my hand like I wasn’t getting a full grip. My pinky would sit even or slightly below the bottom of the magazine. Added this gem to one of my magazines. The extension added enough mass and weight to increase my comfort and confidence in shooting. Knew I found a solution to my issues within the first five rounds sent down range. Will be ordering more to swap out the rest of my spare magazines. Good quality easy to install best price on the market. Fast shipping. What more could anyone ask for. Highly recommended

Purchased for a SW9VE, extension slid onto magazine easily and is held in place by a little retaining screw. Added +3 rounds capacity to 16 round magazine. Have 13 magazines total, all but 3 are 16 capacity (PS: take a look inside a 10 round SW9VE magazine, little surprise coiled up in there!). Have some 17 round capacity magazines as well for a total of 20+1, thanks again Galloway, I'll be ordering more magazine extension for certain! : )

Just received my spring kit and mag extensions. Everything works awesome! This company has the best products without spending a whole pay check. I’m very please with my SD9 upgrades. I will always buy all my parts from Galloway Precsion all day long…

First off, this company has been the quickest with the shipping and notifications! I am overly impressed! The product that i received in TWO DAYS!!!!(amazing and that was FREE SHIPPING) was exactly what i was looking for! the extensions work perfectly with my 3 original magazines... the installation was easy. You will further on get my business and i will surely tell others! Thank You. P.S. I got the notification that it was in the mailbox and was shocked beings that i ordered it 2 days ago... i ran to the mailbox hahahaha

This is an excellent +3 for an original mag, Installs great and looks even better definitely getting a second.
