I stumbled on this listed for WAY too cheap last weekend. The 9mm SP1 version has been on my buy list for some time and I've bid on many but they end up going for 3x what this was.
This example was complete with original case, manual, test target, three 10rd magazines, and spare hammer spring. 1999 date on the test targe.
Notable changes on the Competition models; SAO, magwell, oversized mag release (see latest Beretta USA version for what looks to be a clone of this Vektor design), blacked out oversized rear sight and simple tall front post. Also, the beavertail is way larger than a normal SP1/SP2. Also, the safeties are interesting....they have a hole in them that indexes over the red dot on the slide showing "safe" or "fire". Lastly, the dust cover is reinforced and much thicker and has drilled holes and plug screws, likely for a sight bridge (still looking for info on this).
I'll put a 357SIG barrel in this whenever EFK makes another run. These are 4.6" long so will have to modify a standard 92 barrel to fit.
