I just received my Blackhawk Serpa holster for my 5.7 MKII, yes I said for my MKII.
The
GOOD news...
The fit is typical Serpa, solid feel, solid retention. FAST draw. As with other Serpa models it is modular and can be configured as a duty holster, a thigh holster, and a belt holster.
NOW the
BAD news...
Blackhawk only produced 300 units for the MKII (and apparently discontinued the USG model). The Five Seven Serpa is no longer in production, the last Five Seven Serpa I purchased (USG model) I paid $20.00 for. I had to purchase this one off of eBay for $119.00 and by the time you read this he is probably out of them.
The MKII Serpa is clearly marked REV D on the back of the holster
Why in the hell Blackhawk would go to the expense of manufacturing a mold for the MKII and only manufacture 300 units is beyond me.
