About Builders Kit:
These are called BUILDERS Kits and not called “Assemble Kit” for a reason. You will need to file/sand/polish p80 frames/parts in order to make it work. Esp. for the subcompact, almost 100% of the time you will have to modify the locking block. If you are not capable of doing this then DO not buy these kits. It is your SOLE responsibility to figure out how to install any of the parts you've purchased from us. We can't tell you how to fix a non-resetting trigger, or how to install a slide parts kit. Please do your own due diligence and Search online prior to purchasing any of the builders kits. We will not assemble any slide parts kits at this time. All our build kits will have Channel Liners already installed. If we have time, then we will also install sights (if they're available). You can figure out the rest. Simple google search usually does the job. Again, if you’re not capable of doing this then DO not purchase any of these build kits. We STRONGLY RECOMMEND to go on youtube.com and searching "marinegunbuilder". Watch all of his build kit related videos. It will help you understand what to look for when you're building your kit.

I’m having problems with my slide locking block when I cock it back it gets stuck goin back to normal position
This is a great kit, included everything except the jig and frame rails as noted in the add. All parts were assembled with very little modification to any of them. Awesome quality finishes product and no issues with this gun at the range. Out of the box we fired 300 rounds. Money well spent and unbelievable shipping time. I’ll be back.
This us a great glock for a low price i pretty sure its the lowest around
Did not come with the trigger assessment
It was a pleasure to deal with these folks as they did what they said and said what they did, a rarity in the market today. The product i ordered was of the quality i expected, again a rarity. This was my first time useing them but wont be the last, and.they were qwik. None of that 2 months due to covid bs. So if u want somethimg done right the first time try them. As b4 , o i wasnt a paid schill for this review just a happy camper, for once. Thats all folks, Elvis is leaving the bldg. Rich/ San Jose, Calif.
