I'll agree with Rodan, Tisas B9R is most excellent for the price... for under $600 it's insane how good it is. I actually picked up a full size / 5" and in process of getting it how I want it, halfway there right now. Trigger was okay stock but a bit too heavy and the grip is a bit lacking in stick. That said, I love how it shoots: about 2 1/2" group at 20 yards offhand and POA running 124gr Blazer.
So far I've changed out the grip module to a Warwick Tactical reworked/machined MJD carbon/kevlar composite unit that was on clearance and added the required MJD mag release. Grip level is insane on that module, love it! Also put in a Red Dirt Staccato fitment flat trigger in it and tuned the sear spring to get an incredible trigger pull on it. Adjusted the pre and post travel to get it tight yet fully reliable and now it has a way lighter but not too light pull that is only 0.5mm pre-travel when cocked until you hit the wall. Uncocked there is 1mm total free travel, and when not depressing the grip safety there is absolutely no movement of the trigger at all - rock solid and unmoveable whether uncocked, half-cocked, or fully cocked. Also have a pair of Springfield Prodigy magazines which work great just like the factory mags.
Also have changed to full length Wilson Combat guide rod setup with flat recoil spring (have the 13 & 15lb ones), EGW stainless pin/internal parts set, 19lb hammer spring, and an extended slide release (TriARC). Running an RMR footprint optic on it currently (Meprolight MPO-FR) with an RMSc to RMR pattern adapter plate (from Lakeline LLC). Incoming I have a stainless EGW single sided HD thumb safety, Dawson Precision stainless low-profile mag release button, and the Wilson Combat barrel bushing compensator. I really want the Underworld Arms rail mounted compensator for it (design similar to the HK USP Match comps) and was excited when they released the Tisas Gen 1 version a few days ago - but only for the Commander length (4.25") versions. So Wilson Combat barrel bushing compensator it will be until they release a 5" full length version.

A preview of my 5" B9R in it's incomplete state:

I will say the new Gen 2 B9Rs are a nice upgrade with the MAC (Military Armament Corporation) slide, longer frame dust cover, and bushingless bull barrel setup. The MAC 9 DS-D Comp pistol might be a better upgrade over a Tisas labeled gun though for the features it has - fits RMR optics right out the box, has extended slide release & extended mag release, larger thumb safety, full slide length dust cover, magwell, and of course a chunk port compensator designed into barrel & slide. MAC is the Acura to Tisas being the Honda... and for not much more money. The bang for the buck champ and most everyone says better than a Prodigy hands down.
