Question: Could this be made to fit the Glock 21 (.45 ACP) I am fine with needing longer screws or minor adjustments with a Dremel.
Document: I ordered this to put on a older Glock Gen 1. I wanted to attach a light. The Idea is good, but the quality of the parts is not. The parts would not match up with the screws. I could never get it to fit properly even after taking it to grinder. I finally gave up and have it in the drawer that holds the other Chinese mistakes I have made.
Says glock gen 1 on the box. I sure wish the advertisement said this. I was able to find longer screws, saw them, file them and get it to fit but is was quite a hassle. After that it has been fine.
After purchasing the rail adapter , I decided to read the reviews and what was said was true. This was not made for all Glocks. I would have to make a few modifications on the adapter to make it fit.I could not tighten the screws down to have it secure.Plus was AMAZON's return policy
Fairly well made product but doesn't fit easily even on an original model Glock. The screws are too short and I had to use a grinder to shave off some metal in order to make it fit properly.
This item appears to be well made, but it does not fit my G17 gen. 1. The screws are too short, but even with longer screws, tightened fully, the rail bows downwards at the front making it impossible to accurately mount a sight.
Okay, so a lot of complaints that the screws aren't long enough. I suppose they would fit the Glock 17 gen 1 just fine. Mine is a Glock 17 gen 2 and the screws are too short as well. But am I going to whine about it and grind on the product to mess it up? No. I did a little research and found out that the screws are &#34;Socket Cap Screws&#34; and the description is M3 - 0.5 x 20mm.
Product does what it says, it adds a rail to your gun. I added it to my Glock 26. First, the screws that came with didn't fit I tried squeezing the pieces with a pliers and it cracked. I had to buy longer screws and cut them to length. Second, good luck finding a holster that works well with a light or laser attached to the rail.
This fit my glock 19 well. Very secure I agree with others posts the top screw should be 3/32 longer the bottom screw should be 1/16 longer. the screws provided do work with proper alignment. I gotta couple full turns alternating between lower and upper screws. Longer screws would be easier, quicker, and  more confidence instilling. loctite was added and time will tell if supplied screw will suffice
they need to be more specific on whick glock models it fits it is def not for the gen 3 model 36...its cheap and after modifing it with longer screws it still didnt fit properly then eventually cracked the rail...i only gave it one star because they aint specific on the gen and model it fits
Like the reviews said, it will not fit some guns! Not my Glock 17 Gen 1. Bolts just a tad bit to short. Had to buy longer bolts then grind them down when they protruded too far. A little touch up paint and it looks good. Rail is steady and secure. Then, the laser I had (a cheap one) would not stay tight on the rail. Have not been able to determine if that is do to the rail or the laser.
Answer: yes
