SD40VE

Just a note about the Sigma mags: the Sigma baseplate is not only shaped differently, but its also thicker (this is on the SW40VE ones, not the SW40F which is WAY thicker).

The Sigma baseplate from bottom to the top mics out at 0.263". The SD baseplate mics out at 0.244".

For me this is enough that the Sigma baseplate is just about bottoming out on my SD40VE before the mag catch engages. If I take a second to wiggle it a bit it'll catch, but it doesn't do so as effortlessly as the stock SD baseplates.

I personally wouldn't trust the mags with the Sigma baseplates to correctly seat if I had to change them at speed. As a result I wouldn't hesitate to carry a Sigma mag in the gun, but I wouldn't carry one on my belt as a potential reload mag until I'd switched out the baseplate to an SD one (or sanded down the Sigma plate a bit thinner).
 
Maybe some practice reloading would help? I know what your talking about it does take a slightly forceful shove to seat the mag. I think with some practice it will become second nature to slap the mag in right every time.
 
Its not about force. I can insert the mag slowly up until the baseplate contacts the frame pushing on it and it often still doesn't seat until I "jiggle" the mag body a bit. If I slap one in quickly no matter how forceful about 20-30% of the time it falls right back out of the gun. Like I said I wouldn't care about carrying such a mag IN the gun to start with. Once it locks in its no problem, but I wouldn't carry one on my belt as is.

Swapping the SD baseplate over to those same Sigma mags totally alleviates the issue (I've already tested this) - they seat easily and correctly every time. I've got 3 Sigma mags and 2 SD's, but I'll swap SD baseplates over to the Sigma mags as soon as they become available for sale separately (not sure why but Midway nor Brownells have an SD parts category yet).
 
Maybe it's just me but it seems maybe your mags are distorted in some way. I have 4 and no wiggling required or heard any having that problem.


How about shaving the butt of the grip slightly?

I'm sure that would work if it comes down to it. If I can't find the proper baseplates given enough time I may look into doing that. For the time being I don't really intend to carry this gun nor use it in competition (I used a Ruger LCP and an M&P 9L for those, respectively), so I'm not too terribly worried about it.

Not sure, but it also could be the date of manufacture. I don't know if S&W's really old baseplates were thicker or not, but my Sigma mags are all Law enforcement only marked so they're from at least before 2004.
 
I was considering the M&P compact in 9mm, but this looks to be a good and less expensive option, especially since it is a thinner framed pistol for concealed carry. However, if these some of the suggested upgrades are needed to make it more efficient, why not just go with a shield or the M&Pc?
 
Does anyone know if an m&p magazine fit a sd 40 ve??

NO! They will not.

My wife & I love ours SD's She has 9mm, I the .40. Both with Apex Spring Kits. She has 15# recoil spring, metal guide rod, I have 22# recoil spring guide rod. I polished the ramps starting with 600 grit wet paper, then went to 1500, finished with Flitz. These weapons will now load anything they are fun, and hold great groups at 30'. We just wish we felt more comfortable carrying a large weapon. We are both over 6', yet can't get around the feeling we are carrying a rocket launcher...
