Got a new Mac 9 ds comp 4.25 pistol!

[Mschroeder40]

Just picked this up yesterday. I was anticipating getting it so I bought some extra springs to lighten it up. I put a new 12 lbs recoil spring and a 17 lbs main spring. Also completely disassemble the trigger and polished it up and lightened the sear spring up a little. Plus got after market plate screws and +3 mag extensions. Added a Holosun 507 comp green dot. Plan on stippling the grip once I get my stipple tip in next week. This pistol is pretty awesome, great fit and finish with very tight but smooth slide. I put 300 rounds through it today without any malfunctions. It shoots great groups and I even took it to distance. I shot it @50 yards all the way out to 267 yards just for fun. It took me 5 shots to get on target @267 yards with an impact the first iteration the second was 7 shoots then an impact. The target is 16" x 12". I was pretty amazed with the accuracy to say the least. If anyone is looking for a double stack 1911/2011 this is a pretty awesome bang for the dollar.

Man, that's one sweet setup! Three hundred rounds with no hiccups is big, and hitting at 267 yards is wild. Sounds like you tuned it just right. What kind of ammo were you running for that test?

I did a little stippling job over the weekend. I was running federal 115 gr.

I'm impressed by stippling work such as what you've done. Don

This was my first time stippling. Now I'm going to start on other firearms and magazines.

You got yourself a good piece of steel there, you're already ahead of the game by polishing the internals and getting that slide running light, good work skipping the common mistakes. I'll advice you leave the grips alone, you're talking about stippling the grip, but I'm telling you, take the $150 you were going to spend on tips and find a grip tape kit for it instead. A lot of guys with a new double-stack immediately want that aggressive, stippled texture, but they forget that the MAC 9 DS grip module is proprietary. If you mess up that stipple job, you can't just buy a new $80 polymer module, you’ve potentially ruined the entire frame. Slap some skate tape on it, it gives you all the grip you need, it's cheap, you can replace it in minutes and if you ever want to sell the gun, the next guy won't inherit your amateur stippling mistakes
