[Ming_the_Merciless]

I assume your speaking about the thigh holsters, as both BHPG and Safariland have a variety of holsters. Its not a true apples to apples comparison, because the method of LVII retention is different. Safariland uses a rotating hood, Blackhawk uses the SERPA release. With the Safariland one must remember to rotate the hood back, the SERPA just reholster, this may or may not be a problem based on your level of training.

SERPA PROs
1.) Relatively Cheap
2.) Readily Available (At Least State-Side)
3.) Variety Mounting Options (Comes Stock OEM)
4.) Comfortable (Thigh Rig Y-Harness v. Traditional One Point)

SERPA CONs
1.) Release Mechanism (LVII Can Jam)
2.) Bare Kydex (Wears on Finish of Gun)

Safariland PROs
1.) Felt Lining (Protects Finish)
2.) Wide Variety of Holsters for Different Makes/Models
3.) Wide Variety of Holsters for Laser/Light Combos

Safariland CONs
1.) Long Turn Around Time (Depending on Make/Model/Laser/Light Combo)
2.) No Variety of Mounting Options (OEM Stock Doesn't Come with Accessories, Must be Purchased)
