I picked up a used MP45 midsize today for a decent price and I have two questions. I own 2 MP9’s(FS and C) so I am familiar with the MP guns. Gun supposedly(and looks it) has only had at most 250 rounds through it.
The trigger pull is smooth and light up till the point of the sear break. It feels like a brick wall and takes way more than what “feels” like ~6lbs to release the sear. I tried to compare to my stock MP9C(my FS has full APEX guts so not a fare comparison) and it still feels like its way heavier. This is a 2009 gun(DSN prefix). Could this be an MA sear gun? I havent taken it apart yet. I am going to order an APEX DCAEK next month, but I want to shoot it until then.
I have field stripped it a few times and the recoil spring assembly just falls out when I take the gun apart. It fits in there snugly when I re-assemble, but it falls out every time i dis-assemble. Any clue on this? The spring does not seem “worn out” since the gun is very low round count and the slide seems to have good velocity when released. I cant see anything obviously worn out or broken on the assembly. Should I just call up and order a new spring assembly just to be sure? Seems like cheap insurance.
Also, any clue why the mags are chrome(or whatever they are) compared to the black mags for the MP9. Is it just so you can differentiate between the two?
Other than those two things this gun is flawless. Night sights, 3 mags(2 have NEVER been used), leo gun, original box, etc…
I have a full size M&P 45, so congrats on what I think to be the best hands down value for a 45 auto on the market.
1: The trigger is normal, for some reason the 45 have a stiffer pull at the break point. Your APEX parts will handle this nicely, I doubt you have a MA gun but I guess it is possible as I have never handles an MA compliant M&P.
2: Recoil spring, mine does not fall out when I field strip so I don’t know what is up. Not an issue and if it makes you uncomfortable you can get a new S&W one from speed shooters specialties for like $11.
3: The silver mags are the newest finish and they are nearly rust proof unlike the earlier blued models which were rust magnets.
Enjoy your new blaster, I am totally converted overe to the M&P having sold off all my personal Glocks and ending up with a FS 45 and an M&P 45 compact for my off duty carry gun.
I have the same “problem” with my recoil spring assembly. Unfortunately I don’t have an answer for you as to why. But I don’t believe it’s an issue to be worried about.
Shot it today after giving it a fairly thorough cleaning. Holy SHIT does the trigger suck. Its a nice smooth 5-6lb pull to the sear break point(no grittiness or stacking) and then like 12lbs to get the sear to break. Almost like a reverse 2 stage trigger. Super hard to get decent shots even really slowly. The could that I got off that I felt good on were dead on so I know the gun is capable of good hits. I am wondering if this thing has an MA sear spring with regular trigger springs. My stock MP9C is NOT like this at all nor was my MP9FS when it was stock. I havent yanked it apart yet to see. Its getting an APEX DCAEK immediately.
The stock triggers often smooth out nicely after 1000-1500 shots.
On the other hand, I put in Apex Duty Kits on any M&P that I work on and it solves most all problems, in addition to providing a nearly perfect trigger for a working gun. I have come to strongly prefer the M&P/Apex Duty trigger feel over that of any Glock I have shot. If someone wants better than that, then Bowie and other competent smiths can make an M&P feel very nearly like a 1911.
The trigger pull is actually really smooth up until the point of trying to get the sear to break. I wish I had a trigger pull gauge to see exactly what its breaking at, but it feels like 10-12lbs. Like I said the pre-travel is really smooth and fairly light(which is a contrast to most stock M&P’s, both mine and others I have shot which were gritty and had tons of stacking). Its just at the actual sear break that sucks bad. I am going to yank the sear out and see what spring is in it since like I said I have heard of guys who got MA sear springs and housing blocks while having the rest of the springs in the gun being non-MA and they have almost he same situation I have.
Either way I will get it sorted with a DCAEK and then the gun will be much more fun.
I aint waiting that long. Already ordered a DCAEK for it. It just too different from my MP9FS with DCAEK and I dont want to get used to a completely different trigger feel. Thats why I bought the MP45 instead of say a Glock or H&K or whatever, because I want them to shoot the same.
My M&P45s trigger was the same as yours. Smooth up until the end and then very heavy and not real consistent. As a result, I didn’t shoot it much the first year. I put in an APEX sear and it is now probably one of my favorite triggers. What I difference a little drop in part makes.
My recoil spring does not do the same thing as yours, but as long as it fits snugly when you resemble it, given the fact that it is a captive spring, I don’t think it will cause any issues. It’s not like it has anywhere to go once the pistol is assembled.
The two magazines that came with my pistol were black. The two magazines that came in the mail for free (it was a buy the pistol get two free mags deal) had the newer gray low friction coating. Every magazine I have purchased or seen since then are gray as well. So it is now standard. It looks to be the same coating as the special Beretta desert magazine which is for improved reliability and corrosion resistance.
My M&P9’s trigger measures at 5.5 pounds pull with a Lyman digital trigger gauge. This pistol has about 300 rounds through it, plus another 300 dry fires.
I just picked up a new M&P45 last week and noticed the dramatically heavier trigger in it, just like you observed. My Lyman tells me it takes 8.5 pounds on the trigger before it’ll fire.
Oddly enough, I’m much more accurate with the 45 than with the 9 (shooting 147-grainers). I only have about 150 rounds through the 45 and almost no dry fire, so I’m not sure why the difference in accuracy, but boy that 45 feels even better in my hand than the 9.
