Put 60 more RDS of Underwood 220 HC through the M2.0.
Unfortunately, I had multiple failures to reset the trigger (slide wasn’t going fully into battery). I wonder if I was “limp wristing” a little and not letting the gun completely “reset”. Or maybe the #24 lb spring is too much? I went ahead and bought a 22 lb IMI spring and I intend to install it onto the factory recoil guide. |

Quoted: Quoted: Quoted: I am looking for a cross draw holster to fit MY MP 10mm with 4.62" barrel. Does anyone have any recommendations? Something like the Galco Phoenix is what I am wanting but it isn't made to fit this model. Thanks the 10mm is the exact same size as the m&p 45 and i believe 9mm as well I believe the 9mm is smaller. The full size M&P 9mm is definitely smaller. My M&P 10mm will not fit in any of my M&P 9mm holsters. |

I think the 22# I’m running is more than I need. But I only shoot 180 and 200 gr bullrts |

Getting that bolt unscrewed from the recoil rod was a bbbbbbbbaaaasssssttttaaaaarrrdddd. Still, got it replaced with the 22#. I’ll snag some ammo this week and see if it runs ok.

I’d also disassemble, clean and degrease the screw threads, slide threaded holes, all surfaces of the plate snd the bottom of the optic. Then reassemble with thread locker, let cure and add witness marks to the fasteners. |

I really want one of these, how are they holding up? Does anyone have 2000 rounds through one yet or seen a hard use review?

So I have the 22lbs spring and rod, and the +10% springs in one magazine.
The penultumate round won't feed, consistently. Doesn't matter if I load 5, 10 or 15 rounds. Looks like it and the last round both kick up too high and won't enter the chamber. Any ideas how to fix? |

thanks aero, looks like the average OAL deltas between 220gr and 200gr is ~0.005”
not sure that would contribute to rare FTF issues, but maybe its on the line |

Ok watching a lot of videos on MP 10MM FTF issues reading the comments. One non-MP video is below which I thought was pretty interesting has me thinking im over sprung
I think with the weight of the holosun optic and 22# recoil spring, my slide might be over sprung shooting 220gr underwood. Just swapped out to a 20# and going to give that a run. If it FTF again, I will look at maybe going to a lighter recoil spring, and the Apex Failure Resistant Extractor which should have a more open geometry to allow the case rim to more easily slide in Based on the OAL between 220 and 200gr underwood, I think I would have the same issues regardless of bullet weight 2m30s mark Technical Tuesday: Identifying Malfunctions - Nose Up Jam Im accepting 220gr underwood donations for this testing |

Instead of being squared off it has an angle edge to it to allow for smoother feeding. In our test firearms we were experiencing feeding issues as well in a factory configuration.” so hopefully reducing the recoil spring to 20# and a new extractor will fix the rare (3 out if 100) FTF issues i’ve experienced with 220gr underwood |

Here are some comparison shots between the OEM extractor and Apex Failure Resistant Extractor looking at the ramp/claw where rounds are loaded up from the magazine
Initial observations: - the OEM hook is thinner overall, but the Apex is tapered thinner where the round enters - the OEM hook depth looks longer, but both extractors have their claws fully engaged on the brass rim OEM (left), Apex (Right) Attached File OEM (left), Apex (Right) Attached File OEM (left), Apex (Right) Attached File Im going to put 200rds of ball through it and then test the 80rds of underwood 220gr with 20# recoil spring.

Great news, using the 20# recoil spring and the Apex extractor, I shot 100rds 180gr ball and 80rds 220gr underwood with no FTF issues.
Since I changed to 20# spring and new extractor at the same time, I cant say what the fix was but I do think the 22# and 24# recoil springs were too much, also factoring in the weight of the optic on the slide. My hand hurts If I had to do this all again wanting to shoot 220gr underwood with an optic starting from a new gun purchase: - upgrade magazine springs to springer extra power - upgrade recoil spring to wolff 20# w guide rod - purchase metal CHPWS optic plate |

I have been using a 20lb spring since I purchased the gun and with the factory extractor have had no failures with about 500 rounds from 180 to 220 grain. I have not upgraded the mag springs yet, but haven’t felt the need for it yet.

Had mine about a week.
Recoil with 22lb and 180 fmjs seem lighter than factory spring. 50 rounds 180lb 20 rounds underwood 220 hard cast 20 rounds underwood 180 fmj Only issues are with the 220 hard cast. Magazine falls out of gun. Mine is the safety version and I know my thumb is not hitting the release. Looks like it’s a magazine issue with the big hard cast bullets. Anyone have solution? |

I indeed inserted a full mag into a closed slide. I tested just now and mag catch doesn’t close all the way when I do this with 15 rounds in mag. 14 is fine. I did remove mag catch to clean it. The spring is embedded into the frame and can not be replaced. I did try to bend it a little to increase tension. I’m thinking of 3D printing a little piece of TPU to slide onto the spring (it’s just a steel rod) to increase tension. I’m positive I’m not hitting it. Mine is the safety model and thumb is not leaving safety. |
