Replacement 43x slide
Quality looks nice and it is smooth, but gave failure to feed issues with 115 and 147gr remington ammo. Even swapped to a glock branded spring..
Wont load
Firing pin extended past the bolt face. Would not go into battery.
Failure to feed
Bought the ported option for my 43x. Ports work great, but after the 2nd mag it started having failure to feed issues. By the 5th mag it was unusable. Put the factory barrel in and no problems. Kept the slide on because the serrations were much better than the oem slide and mine is not a mos version.
Failure to Feed
Installed on an SCT lower frame. Had continuous failures to feed rounds. Moved the slide assembly to a PSA micro dagger frame, and to a genuine Glock 43x frame with the same result. Replaced the barrel with a Glock barrel and it functioned properly. You should consider the cost of a new barrel in the price of this item. I do not recommend.
Unreliable
Ill give 2 stars because the fit and finish look good, on the first assembly I received i was getting failure to geeds because the round was getting stuck under the firing pin, called the tech line (they were great) and said that shouldn't be happening and they sent me out a new assembly(great customer service). New assembly the exact same issue. I cannot recommend the slide assembly unless you are willing to try and work on the pistol yourself or have a smith look at it.
Needs work
Fit and finish look good, but went to the range and kept having failure to feed malfunctions. The rounds kept getting stuck under the firing pin. Called the teck line with brownells (they were great) and said that souldnt be happening. They sent me a brand new one (fantastic customer service) but again had the same issue. Found online people were having the same issue and the fix is they were snading a bevel on the bottom of the firing pin so the round would push it out of the way. I have a oem firing pin on the way because it has a bevel from the factory. This issue needs to be adressed by brownells imo.
Not Reliable
The upper looked great when i took it out of the package and I was excited. Inspected and lubed everything and headed to the range. Round 3 I had a malfunction. Figured it was just new. Continued to shoot and had several malfunctions. Ended up shooting 300 rounds and still was malfunctioning. Ammo was Speer 124gr Lawman, so it was not the ammo. Returned the item
