Has anyone had any problems with the plastic base breaking off of the botom of the mags? I'm doing tactical reloads and after 40 to 50 waist high drops on concrete with partially full mags the plastic breaks away from the metal. I have had 3 out of 8 break and only had the gun for 9 weeks.

What do you think is going to happen if you dropped them that many times on concrete? Get mag bumpers/pads if you plan on doing that...

LOL..As a matter of fact I just broke my 10 rounder. But I was doing timed draws and as I came out and up my full mag went flying. Everyone laughed but I didnt when I picked up my mag. Post up if you phone into S&W and see how easy it is to get some replacements, I havent had time yet.

I threw a fully loaded Sig 226 mag across a USPSA stage once. One of my first times out, and I was trying to hurry...pulled it off my belt and as I was bringing it to the gun, it slipped and went flying across the stage. Learned a valuable lesson that day

As for the broken mags, dropping plastic (with a nice metal weight) on concrete will break them. Might find some rubber sheets at a hobby or craft store that you can cut and glue to the bottoms to absorb the impact. Will definitely help prolong their lives. Or figure out some sort of parachute rig

I've been dropping my 15 rounders on conrete floors at an indoor match twice a month since I got my holster.

No signs of undue wear and tear yet.

Thanks for the suggestions on "bumpers" and such. Unfortunately IPSC-Production doesn't allow additional stuff that is not original from the manufacturer.

I called S&W and they said they would replace the bases. They are out of stock and expect some in 4 to 6 weeks.

Win,

I would ask your local club leader about adding a rubber base pad and tell them why. I think the reason you want to add them is understandable and they do not give you an advantage in any way. I think the spirit of the rules would allow them.

I did some looking and found the differences between IPSC Prod and USPSA Prod rules interesting.

Win,

I also wanted to let you know Brownells has them in stock here

I know S&W said they'd send them free, but if you don't want to wait, they're only $1.68 at Brownells. It doesn't say if they're for the limited or full capacity mags, but i'm guessing based on the schematic picture that the one's Brownells has are for the full cap.

**EDIT** Ok so last night I was a little out of it. Might be worth a call to Brownells to find out if these are the 10rd bases or if they're not, do they have 10 round bases. And if nothing else, this is posted as an FYI for anyone else.

TBoliv,

Thanks for the info.

As raz mentioned, he has been dropping his 15 rounders on the concrete with no problem. Unfortunately I'm in Canada where we have a 10 round mag limit (ya, let's not even go there ...) so I have to use the ones that are 30% plastic on the bottom ... most of the problem I think. It would be nice if S&W would "factory limit" (with a pin, rivet or something) a 15 to a 10. Might help to avoid this problem!?

I'm in California, so I feel your pain. You being in Canada also explains the IPSC rules instead of the USPSA rules.

I'd still talk to your local match director (or email an area director) and ask if rubber base plates would be illegal or allowed in the spirit of the rules.

A similar discussion came up on another forum I frequent where someone suggested a solution they came up with. They went to a cobbler (shoe craftsman, not the pie) and got some 1/8" rubber and cut to fit. They attached them with contact cement. Even to do this to your "practice" mags and not your "competition" mags so as to limit the damage to all of your magazines.

It's still not a robust design compared to a conventional magazine of any capacity.

Add me to the list of people who wish S&W had just gone to some sort of internal plug rather than the more complicated/less robust/godawfully ugly current 10-rounder.

anyone have pics of the 10 rounder, and what is breaking? Just curious. The 15 rounders have sopme pretty thin parts, but seem to be holding together.

A little hard to see (at least on my screen), but the line across the magazine is where the metal magazine ends and the "solid" plastic bottom begins.

ok here is thread that has a pic of the 10 and 15 side by side. If you look at where the gap is in the first pic that is where mine has cracked.
