Here's my Glock 23 after all is said and done. All the parts have come in and have been installed and/or handfitted where applicable. All custom work was done by me, and meets all standards to shoot IPSC Modified Division Major (with my handloads), and IDPA Enhanced Service Pistol Division with my stock barrel. Barrel the barrel is a Bar-Sto 4.75" SS National Match barrel with a threaded end, hand fitted (by me) to the receiver. 2 port compensator is aluminum with a matte anodized finish and threaded to the barrel. General Glock OEM extended slide and mag releases. Lightning Strike stainless steel guide rod and ISMI 20# spring. T.H.E. Accessories brass magwell treated in a black nitride finish and custom relieved front area for grip comfort mated to a customized Seattle Slug. Pearce +2 magazine extensions (legal for use on Glock 23 due to Glock 22 mag compatibility). Trigger Group Glock OEM 3.5# connector and smooth trigger. Lone Wolf adjustable trigger overtravel stop. Wolff competition trigger spring set; 4# striker spring, lightened striker safety spring, heavy duty trigger return spring. Melt and polish of trigger components. fun build. took me longer to get the parts than to fit the parts. i have a Firepoint/J-Point/Optima 2000 red dot sight on the way, but may forgo it as i'd have to switch the rear fixed sight out to mount the red dot sight... and it's not legal for IDPA use. i'll install it if i end up switching to my Sig for IDPA. the bottom line: a tad over $500 in parts, and about 8 hours of install and adjustment time. i charge $35 minimum for the first hour and $50 thereafter, prorated into 15 minute increments... helps get in small, fast business by charging less for the first hour. just a hobby, really... dont even have an FFL so i cant accept shipped in guns.
