i need advice on choosing a polymer semi pistol? the m&p series or the sigma?
Take the M&P - it is professional grade.
i know the m&p series had rust issues
Never heard of that. They have stainless slides and barrels with the melonite treatment. You have to work at it to get it to rust.
& they dont have stainless steel mags.
True. Wipe them off.
and there were failure to feed problems too.
Never heard that one, except as operator error.
the sigma has no rust issues?
never heard of any rust issues with SIGMA
and has no failure to feed problems?
I have heard of some feed issues with SIGMA, but generally they work well and if it does not, S&W will fix it.
and it has stainless steel mags too.
Not correct. SIGMA has carbon steel mags finished in a teflon nickel coating.
can someone give me advice please.
