This a slightly used Glock 19 gen4 (used value at $420) with an Agency Arms frame-stippling (cost $400), Agency magwell (cost $100), Overwatch trigger and Ghost fitted trigger-bar ($160), a milled and cerakoted slide ($350), an S3F fluted barrel, and Heinie Straight Eight sights ($140). -- I have over $1850 in this gun, and the trigger is THE BEST trigger I've ever felt on ANY GLOCK (and I'm a trigger snob). People are always shocked by the trigger pull. It's about 4.25lbs, but feels a bit lighter. It probably has about 1200rds through it (mostly 124gr American Eagle) and it's never had a jam or problem (except an aftermarket ZEV extended mag-release caused mags to drop every time it was shot--so I went back to the OEM mag-release). -- I'm in NO HURRY to sell this. It's my favorite pistol in the world. You might can find someone to do this nice of a stippling job and even the "gas pedal" cuts for $250, and I know you can find a cheaper magwell, sights, and some nice milling (though I do not like any holes milled into the slide of a gun, since it's a place for junk to get inside the gun). But having messed around with a lot of gucci-glocks, I've never had the parts add up to a greater sum like with this gun. If you think I'm asking too much, you might be right. Agency Arms IS pricey. I won't respond to lower offers or trade offers; however, if you want to meet up, see the gun, and dry-fire it, I'd be happy to meet you. My thinking on value is something like this: ** Glock 19.4 used = $440 (cost $550) ** Stippling (Agency does the "gas pedal" the best, and also opens up the trigger-guard from the inside to make it larger, and undercuts the trigger-guard nicely) = $160 (cost $400) ** Agency Aluminum magwell = $60 (cost $100) ** Overwatch trigger = $80 (cost $140) ** Fitted Ghost trigger bar = $20 (cost $30 new) ** Slide milling and cerakote = $100 (cost $300 -- makes it look less blocky, functional serrations) ** Heinie Sights = $80 (cost $140 -- they're almost a year old) This "used value" equals $920...so the price is $850 even ($80 less than half of what I have in it, not counting all the shipping costs for parts and work). ** I'll sell the gun for $800 without the HEINIE SIGHTS (since I know most people have a favorite style). ** Again, the trigger will impress any glock owner. I have perfect feedback on arfcom, gunbroker, and ebay, and will be happy to send those links to you, and happy to meet you. It's backwards compatible with most Gen 2, Gen3, and Gen4 parts.
