Hi everyone.. I just bought new M&P 9mm on gunbroker. I think I got a good deal. Paid a total of $620 including shipping , FFL, background check and got the full sized 4.25 9mm M&P law enforcement model, that comes with 3 17rd magazines , Novel-Tritium front and rear night sights as well as a $50 rebate or 2 17rd free magazines (I will choose the latter) from Smith & Wesson. Also, the gun does not have those annoying internal locks and the magazine disconnect safety. Even though the magainze disconnect safety seems like a nice feature to have, I just fear that this type of safety may cause my gun to malfunction when my life depends on it. Anyhow, I got the setup I wanted, never easy to find what I want locally in Oregon. I feel like I got a good deal, and avoided the Pro series that came with 1 mag less and had an additional price of around $40 or so. My plans right now are on purchasing the APEX M&P Duty/Carry Action Enhancement Kit (DCAEK) for my M&P 9. https://apextactical.com/store/product-list.php?pg1-cid11.html Unfortunately, I am not very saavy in gunsmithing and really don't have the equipment or knowledge to install the better parts into my gun. What I like to know is how much should a competent gunsmith charge me for installing the parts of the kit? I know some smiths around here can give you the runaround, so I like to know if anyone has had this done or has good ballpark figure? Also, does anyone know any good gunsmiths in the Portland, OR area who is experienced at doing this type of worK? I'd be interested in any referrals people can give me. I have heard nothing but praises about the improvement that the Apex kit has made to the M&Ps, many claiming a much superior trigger and reset then even the more spendier and sexier name semi autos. I figure I may hold off on doing this, but was considering maybe just doing it now.
