P2000SK V3 in 9mm. This is my fifth HK pistol, and all of its safemates are DA/SA variants. The SA trigger in the SK is more similar to the P30 with respect to pre-travel and reset, and less like the HK45 variants which have a shorter reset in SA. All HK DA triggers are virtually identical between the P30, USP and HK45 variants. Their double action triggers are long, heavy and very safe for concealed carry.
A couple years ago I was torn between the SK, G26 and M&Pc. I purchased the M&Pc because it had slightly more favorable dimensions for carry, larger capacity and a longer site radius. Cost was not a consideration. The M&Pc was reliable and durable, but S&W and Glock are simply not HKs when it comes to fit, finish and drool factor. I'm a man of middle-class means who appreciates the finer things when they are priced within reason. I am not a Borg who is blind to aesthetics. HKs are gorgeous, functionally superb and priced well within my means.
Comparitively speaking, the SK is slightly more accurate at longer distances and has less felt recoil than the M&Pc and G26. It accepts P30 and USPc mags, so mag capacity isn't a deal breaker when you can carry a back-up 15-rounder on your belt or stuff an SK 10-rounder in the change pocket of your jeans.
My overall impression of the SK is that it is a mini P30 with carry enhancements to the grip and mag release. It carries very well, and the DA trigger affords a level of confidence and peace of mind I never got with striker pistols such as the M&P and G26. If you spend a little time learning to roll the hammer during your press out, the DA trigger is equally as fast out of the holster and on the target as a striker pistol or SA carried in condition 1. People complain about the long reset in HK SA pistols, but my shot timer shows similar splits with the HK trigger as I've run with a Glock or M&P with Apex trigger kit.
