    Glock 42 si mag extension

    I love my si magazine extensions!!!!!! 2 extra in the mag with one in the pipe brings me to 9 for an edc with no extra mag needed. Not too shabby! No issues with feed if you keep the same springs you had. Cheers!

    The extra length is great for a larger hand bonus 2 rounds still compact for cc.

    Excellent, with one caveat

    Highly recommend especially for those with larger hands. However, the spring/locking plate that comes with the product is too thick and 2 extra rounds will not fit. The fix is easy, though. Simply using the old spring/locking plate will allow the extra round.

    Perfect fit

    The product was easy too assemble and fit just right. It made a big difference on my grip of the weapon. I have yet to test it out at the range but look forward to it.

    These extensions are a PERFECT fit!!!!!

    These are the BEST extensions that you will EVER find. Stay away from the machined versions that have the hex screw that sticks out as it could, from my research of a number of magazine extensions, cause issues with seating the mag in the slot on the 43. These are super easy and quick to install. The incredible grip makes it the perfect combo for your 43. Having a "+2" is even better BUT only good if you can get an improved grip that these mags give you.

    took me all of 2 minutes to install. Works like a charm. Would definitely recommend.

    Extended mag capacity.

    When +1 isn't enough, but +4 would give away your concealability. This +2 magazine extension is just the ticket . High quality product get one for each magazine and you'll be carrying 16 rounds + 1 in the chamber, for a total of 17 rounds.
