After a month or so of hemming and hawing I purchased a Umarex S&W M&P 40 (the GBB version of course) to replace my beloved Cybergun Sig SP2022. The SP2022 is a wonderful pistol, and fitted with a rail mounted laser sight it's been my "deterrent" gun.
The M&P appears to be a nice pistol, 'shoots in the 300FPS range, and the build quality seems to be pretty good.
As with all of my gas-powered guns, I had put the obligatory drop of Crosman Pellgun Oil on the tip of the first Crosman CO2 cartridge and the CO2 had leaked out over night, which did not surprise me. After installing the 2nd cartridge (it's now been 3-days) the gun sealed up fine.
I'm still learning the intricacies of the M&P and since it's Saturday I decided to spend some time today working with it.
One of the first issues to come up was upon field stripping, a small strip of silver tape was scrunched up between the slide and barrel. The only logical explanation for this piece of tape is to protect the black paint on the breech from scratches when the slide cycles. It's a "cute" idea, and I'm sure that though it works great for "demo" guns at the LSG, the reality is; That piece of tape is eventually going foul something (barrel, guide rod, or..) and most people aren't going to want to have to "field strip" a BB gun that they just spent $80.00 on. I have to wonder how many of these guns have been returned as defective due to this (as with most of the pistols that I own; I polished the breech and barrel on my M&P so I'm not concerned with minor scratches on the breech).
The BIGGEST factor that kept me from purchasing a Umarex S&W M&P 40 sooner is that in EVERY YT review it shoots low, and we're talking 2" to 4", which to me is completely unacceptable! Now what nobody realizes or makes mention of in their YT reviews (and there's no mention of it in the owners manual either) the Umarex S&W M&P 40 has an adjustable hop up adjusted by a screw in the bottom of the barrel assembly. Now I have yet to shoot any BB's thru mine, I'm hopeful that hop up is in fact adjustable to correct for elevation
One of the big complaints I've read about this gun is the the lack of a catch on the magazine to facilitate loading BB's. In the next week or so I'll try to look into it and come up with a DIY fix, do not expect the manufacturer to address it anytime soon.
Things that you're going need:
1. A good pair of shooting safety glasses.
2. A tube of Crosman Pellgun Oil (This is one of the most valuable upkeep/maintenance items that you can get for trouble free performance).
3. CO2 cartridges, I only use Crosman brand in my guns due the CO2 cartridge seals are broken in to the shape of the Crosman cartridge tips.
4. 4.5mm/.177 cal BB's. Brand is going to be your choice I have bottles of Daisy Copperheads, Daisy Match Grade Avante, and Excite Smart Shot (copper coated lead) BB's.
This gun is a keeper and is fast becoming one of my favorite air pistols. I had the opportunity to run a few magazines thru it last weekend and the gun does shoot low, I haven't had the time to modify the rear sight for elevation. The shot grouping at 30' is very good. I mounted a laser sight and a rechargeable flashlight. The gun will fit a Bulldog Cases holster (large) with the laser installed if you wet mold the holster. The loading spring on the magazine is a finger nail cracker, though using DIY speedloaders made from Bic pens it's manageable.
6-months later and I like this gun so much that I purchased another one! The first one has now been cannibalized for parts in order to convert my Airsoft (6mm plastic BB) M&P 9L Perfomance Center (Extended slide) to use 4.5mm steel/lead BB's. Though this gun is sold under the Umarex label, it's manufactured by KWC and the internals are identical.
