It’s my first FRT and I’m installing it on a Gen 4 Glock 21. I got it in but the slide is still sticky or you could say catching. I trimmed the oem trigger connector already and a little bit of the trip. I ran it then night I got it and could only get about 3 rounds through before it catches, or sometimes even 1 before it stops. Any help is appreciated.
