I have both a Simply Rugged Sourdough & Silver Dollar and they are excellent strong
side holsters, in the cross-draw role using the 3rd slot they are only passable. This
has nothing to do with the quality of the holster itself and only speaks to the compromise
that holster makers have to deal with when making a versatile holster, i.e. the 3rd slot.
Due to back issues I only carry cross-draw so
the following only deals with that style of carry.
Below you will see a SR Silver Dollar & a Mernickle cross-draw holster, both holding guns
with 3" barrels. In the photos you will see how the Silver Dollar doesn't support the bulk
of the gun's weight, which allows it to easily cant out from the body, especially when
bending forward. On top of that the gun, in this case a Ruger SP101, will also tend to
move in & out during physical activity even when your belt is snugged up good & tight.
Based on my experience the cross-draw role for the Silver Dollar & Sourdough would
be better suited to very lightweight guns with short barrels. The more weight you have
and the higher the weight is from the support of your belt the more your gun will want
to move around on you, in this case it generally wants to cant out away from the body.
Edited to add: For the record, the belt shown in
the photos was also made by Rob at Simply Rugged.
