407K/507K are direct fit with no plates.
About as thin and low profile as you can get. |

 When I shot the rock at the gathering I knew I was going to buy one when it was available with an optic cut and this weekends blem deal sure seemed like the time to do it, can’t wait to get this in hand, just in time to carry during bow season which was my first thought for its purpose when I saw it. Also should have plenty of mags!! Just needs a Holosun, light and holster |

So help me out, the 407k/507k is a direct fit but I need shorter screws. But the full sized 507c models will use the included Holosun/RMR plate? Even if it fits with the adapter plate, Is the full sized RMR/Holosun to wide (ish) and stick over the slide edges, or is it ok?

Swapped the Holosun 508T out for an RMR06 to cut the weight on the slide.
Still having issues with failures to eject for rounds 23 through 12-10ish with the first 5-7 either failing to even cycle back fully, requiring a simple hand cycling of the slide, or leaving the fired case in the chamber and trying to load a fresh one, giving a really nice type 2 malfunction requiring all the pistol clearing fun. Going to pick up a few hundred rounds of factory AE or FNH to see if it’s my handloads or the gun. Stupid fun when it runs, but spending more time locking the slide to the rear, dropping the mag, dropping the slide to get on the fired case again, and then cycling the action to eject the fired case and put a new round in the chamber is no bueno. |

Saw this deal on Thursday last week and it's arriving at my LGS tomorrow. Not bad 6 days from order to delivery in Tampa area. Had to grab one with basically 8 magazines free on this deal. From what I've read, PSA blems are not visible to most people.

It’s definitely wide and has no chance of cowitnessing. Also pictured is a 507K on a Glock 48, which is slightly slimmer, and from the looks of it, the 507K would mount a lot lower, giving you the possibility of a cowitness. I Do like the larger window of the RS 10, versus the 507K, but the 507k is prob gonna be a better fit for this slide. |

Got a chance to run 50rds of Federal 40gr FMJ through two 23+1 runs and 2 random rounds.
The pistol had been cleaned and lubed and I was shooting unsuppressed with the RMR on it. Round 1 failed to eject like my handloads. After manually cycling the action the other 23 rounds fired and ejected fine with the sliding locking back. I loaded the other mag, put an extra round in the chamber, and it ran all 24rds fine, though the first piece of brass did seem to eject less violently than the next 23. The final 2rd mag was all good. I wanted to put another 100-150rds through it but the rain showed up. Another guy is getting a similar first/cold gun FTE issue with the Ruger pistol, but he’s also using handloads and the lacquer might be his issue. I’ll put at least another 100rds through it, firing 23+1 each time, and letting the gun cool so I can try to determine if mine also has a first round/cold gun FTE issue before contacting PSA for an RMA. |

First round (especially when loaded +1) has the most friction from the top round in the mag dragging on the slide as it cycles. Weak ammo almost always has more problems with a full mag. Not too say there isn't something up with the gun. If you plan to run AE, you want it to cycle AE. |

Totally understand the added friction of a full mag under a loaded chamber, but the second run of 23+1 working while the first one barely moved the slide is odd. I’ll ultimately resize my handloads more to get them to chamber and extract, the AE was just the cheapest available factory ammo and it’s never given my SBR’d PS90 issues in the past. |

Does the Holosun 507K need shorter screws for the Rock to function or are they too long for tightening it down? I just installed one and the screws are tight. They MIGHT be shipping shorter screws. It SEEMS to function fine. |

The ones that came with my 407k bottomed on the polymer striker housing inside the slide. I could have cranked it down but it may have damaged it.

NICE!!!
The muzzle climb was less than on my Ruger 57, the recoil was less. Accuracy was damn good Grouping was good To make a long story short it out classes both the Ruger and the FN 5.7x28mm MK III and for less money! Far less than the FN!
