Let me preface this by saying that I own, wear and enjoy holsters by DSG, JMCK, Mastermind, and previously, Tenicor.
That said...after daily usage over a period of several years, (decades, actually), I've come to the conclusion that for me personally, the best overall holster belt attachment for a combination of comfort, concealment, security and convenience...(after trying various metal and polymer clips, hooks, Pull-the-Dot, DCC, Monoblock et al)...the one that I grab 9 times out of 10 is the simple but effective clip as pictured on the DSG Orions below:
Is it perfect? No. Since it is a 1 3/4" clip and I wear a 1.5" belt it does allow for a small amount of movement on the belt...preferred by some, shunned by others.
However, I have come to the realization that while not the flavor of the week, or heralded far and wide online or in the print media, it just simply works.
It's easy to don and remove. It stays on the belt. It doesn't print like PTDs. It isn't finicky to install or remove or realign like some DCCs I have tried etc etc.
So, there it is. Sue me!
(I guess I am old school after all.)
