M&P Mag Basepad Extension for 10rnd full size mags

Recommended Posts

Hi guys,

I'm a fairly new competition shooter, having shot a few IDPA matches and a single USPSA match with my M&P9, SSP in IDPA and Production in USPSA. I've been fiddling with the idea of dropping a magwell onto my gun and shooting Limited 10 (minor). I know I'll get my clock cleaned by the guys shooting fancy 1911 types, but I get the floor wiped with me shooting in production anyway, so I'm utterly unconcerned about this. I've also read about 9mm major, but I don't know if the gun could handle it and considering I haven't seen any pistol powder in ages, reloading for it probably just isn't going to happen right now.

I'm curious if there exists such a thing as a slip on base pad extension. The M&P 10rnd neuter mags use a compact tube with an extended basepad. Since I live in Massachusetts, I can't use anything bigger than a 10 rounder in one of these, so the usual route of adding a basepad that adds more capacity is a nonstarter. I could sell it and buy a glock or shoot a 1911 or something, but I'd rather just use this. Does such a thing exist? I've thought about maybe sticking some sugru or something on the basepad to extend it, but I'm not sure how that'd hold up.

Any ideas?

Thanks!

Sean

Too bad you're not shooting a M&P 40. I have both 9 and 40 10rd mags, and putting the 9mm base pads on the 40 mags make them work with the SSS magwells. I live in NV, but when in Cali, I have to play LTD-10.

I wonder if you could swap the followers and base pads onto a 40 tube and make it fit.

ETA: nevermind, that'd put me over the 10 round limit probably. Good to know if I ever get a 40, though, thanks

Get a role of the 3M double-sided automotive tape. Depending on the look you want, either tape a compact basepad on top of your current basepad, or cut a plastic/rubber block and use that to extend the length of the magazine. I have done this with some 1911 mags after I added a magwell, and they hold up fine in competitions being dropped on the ground as well as cement floor.

I was considering something like that. Basepads are all of 2 bucks or so. Do you have a problem removing the basepad? I'd think that you'd have to get the little hole lined up and get a long punch to remove it.

The 3M tape is easy to poke through, so after you tape your block on, you can poke it with a protractor, or drill a hole through the tape and block that matches the location of the mag's baseplate. Its easy, cheap, works well, and does not permanently alter your mags.

Awesome, sounds good. I have a magwell en route, time to find some automotive tape and some sort of pad to attach. Thanks!

If you have a dremel, you can get a dollar-store plastic cutting board. They come in multiple solid colors and slice up nicely.

I do, and really, why have a dremel if you don't use it to slice up random things whenever the opportunity presents itself? Good call on using that, I was trying to see what I had lying around the house. I need to get the magwell in to see how thick of a pad I'll need, then it's chop chop.

Here is what I do for my M&P40 with the SSS magwell. You could do something similar with the 9, it just may need a little trimming or another layer. You can order the basepads from S&W for a couple bucks. SKU 279010000

Looks good. Is that grip tape wrapped around the base? If I haven't gotten this setup by the time I get to a match, I may have to check out one of your mags. I'm assuming the 9mm tube is shorter than the 40 tube. Looks like the first steel match at WPRC is in June, unsure when USPSA gets rolling there or at HSC.

I also need to decide if I'm going to change out the sights or something. With just the magwell, I can pull it and shoot production or IDPA (I know, eisenhow ;) ) with different basepads. The other thought is to find a complete 40 pro slide...

For right now, I need to get out to the range and shoot.

Thanks for the tips, everyone, I've got some minor fabbing to do it seems.

SeanW, ah I didn't get the connection, I didn't realize it was the Sean W I know. The basepads are stippled, it's amazing what a little patience and a soldering iron can do. Are you going to the pistol league banquet tomorrow? I can bring one with me to show you if you are.

The Shooting Internet is a pretty small place, right? Unfortunately, I won't be there. Things are busy with the baby, and I wasn't sure how busy it would be.

My current project is a full volquartsen swap on my mkiii, so if I haven't gotten around to this by the time we start up practices for bullseye, I may be able to look at it then.
