Strike Industries +5 Extended Magazine Plate for G19

Outstanding product at an amazing price point with top-notch service from Primary Arms.

Bought two of these and put them on my Glock gen 5 mags and only gained one additional round. I put two different extensions on two different gen 5 magazines and came out with the same result. I fail to see that I installed this incorrectly as the rounds still fill in normally and feed correctly. Some people may have had different results, in which case I would like to know how to correctly install this product. Seems like the company threw it together to make a quick buck off the ammo boom. Buy with caution.

Honestly, I didn't think it would be any good, but since the mags were polymer I decided to give it a shot. I like it and plan to buy more. Feeds reliable and I have no problems with it.

Very well mag extension for my G19 gen4. Works out great and looks good. Oh and did I mention..+ 5 baby!! Great and affordable. Had it sent thru USPS received it 3 day later, worked out good. Will be buying more soon

Little hard to put together without instructions. Having a Glock magazine tool makes it tons easier.

Easy install, actual +5, functional and the look is cool AF.

Great looks, fit and finish, perfect if you have a Magwell. Only downside, added only 1 round to my Glock 23, 13 round magazine.

SI +5 EMP for G19 is perfect. I'm very pleased with the product. Thank you, Primaryarms for excellent service and fast delivery.

I recently bought these for my Glock gen3 G23C. Description states, "The Strike Industries Extended Magazine Plate is designed for either Glock 19 or 23 handguns. In the 9mm G19 it adds up to 5 extra rounds and adds up to 4 rounds for the .40 caliber G23." Once installed I was only able to add 2 more rounds to the 13 round original capacity, which only allows 15 rounds total. Despite the lack of ensured capacity of +4 for Glock 23, the price is unbeatable to other brands. Would be great if the capacity met the actual description. Hopefully the company is aware of this issue.

Works as described. Be very careful tighting the screw. The polymer is thin and the threads will break/ pull female side of threads out of the polymer with little force.
