This barrel is high quality and a simple swap to make your Glock 35 shoot less expensive 9mm. I've put a thousand rounds through this barrel on my Glock 35. I ONLY swapped the barrel and no need to swap out any parts so that your Glock 35 will shoot 9mm instead of the stock 40 cal. I've been using this barrel in USPCA shooting and it's very accurate.
This is a great optics ready replacement slide for the Shield 9. I live in CA where we are limited on the sub compacts we can get that are optics ready. I installed this on my Shield along with the Apex Apex Tactical Specialties Action Enhancement Trigger and Duty/Carry Kit. It fired flawlessly and will be mounting a 507K red dot on it.
I also really like the fact that is has a loaded chamber indicator hole on the top of the slide to verify a round is cambered. I carry CCW with one in the chamber and like the fact I can glance down to verify a round.
I've put 50 rounds through it so far with zero issues. I highly recommend if you want to put optics on your Shield 9.
I went and shot my Shield 9 after installing the Apex trigger, and for me the difference is pretty significant. My double-tap/follow-up shots and faster and feel so much better. The trigger reset is clean and crisp. I'm very glad I did this upgrade.
Caution & the downside. The Shield 9 disassembly and trigger installation was not easy. If you are going to do this install yourself make sure you have the right punches and use roll pin punches. The sear housing was difficult to get in because the lower corner kept wanting to dig into the polymer frame, but I finally got it in.
This is a great kit, but I feel it's over priced for the parts you get. This could be my ignorance not knowing the labor into machining these parts.
I thought that Talon Tactical Tool was going to be included for installing installing the new spring and striker safety.
All-in-all I am happy with this kit, and the difference it makes in the trigger is very noticeable to me, especially in double-taps and rapid fire.
