I picked up one of these G17 slides(https://lonewolfdist.com/complete-sl...rel-assembled/) to turn my old duty gun into a red dot gun. It would not group at all. I started to think they were closing these out because they had issues. I would shoot ten round groups and would get one or two where the dot was zeroed and then the rest would look like a shotgun pattern. It could be due to the barrel fit, or something else with the slide, as when I first got it the slide got stuck and I had to push on the RSA to get the slide off. When I would do that the RSA would be disconnected from the barrel. I tried two different lowers (including a timberwolf G17 frame I had) and I tried a lone wolf standard barrel and a regular G17 barrel. That upper would not group at all. I did try another RMR the next day to make sure it wasn't an issue with the new SRO I bought and I had issues even with that RMR installed.
I contacted their customer service by email as it is the weekend, so I will let you know what they say, but I would stay away from these slides/barrels until I get more info. It seems like either I got a bad one, or they were on sale because they aren't any good.
Has any one else had one of these?
