I have shot all types of ammo with mine and have no problems at all with any of it. but have also found the CCI AR Tactical to be the best. well worth it in my opinion.
I own a M&P 40C. I love that gun as a carry gun in the summer here in Arizona. Only thing I would recommend is to go and purchase the Trijicon HD sights with the yellow front. Amazing for both day and night. Very easy to accuire the front post easy in the day also. I can send you pics if you...
I use the S&W Micro 90 light. It is very. Small yet very bright & was only $80 @ my lock gun shop. Also seen it for about $90 @ Cabela's. It is very easy to swap from any gun with a rail back and forth with no tools needed.
Go with a Midwest Industries butt plate adapter then get a Magpul MS2 sling & the rail attatchnent set up. Will post pics of it later. Have that setup on mine. Can easily go from single point to traditional sling with ease.
I have the Trijicon HD night sights. Highly recommend them. I have pictures up on the SIGHTS. if you want more pictures or have any questions feel free to message me.
It is the ammo I have used nothing but Hornady Critical Defense loads in all of my carry weapons and never noticed a mark or a dent as you call it. try using those.
I own ALOT of 1911's and love them all. I also own a M&P 40C and a other M&P's. I put the Trijicon HD sights with the yellow front sight on them all.I posted a pic of them on the SIGHTS page. I love them and put them on all of my M&P pistols. Very easy to get on target fast with those sights...
Had them installed on all three of my M&P's. They all shoot to the exact POA! Cost about $25.00 to have them install at my local gun shop. Pictures are of the sights on my M&P 40C.
Go with a Midwest Industries end plate adapter. Then spend the money for a Magpul MS2 sling and a Magpul RSA. Then you have the option to run a single point sling or a standard sling. If you want pics message me & I can send later.
