I've may have caught the bug to get a leather holster for strong side carry. I don't know which one I want to get yet but was curious at the different designs and what causes retention. Also, one thing I love about kydex is that click it gives me when the gun is fully seated. Is that possible with leather and if so is there anything I should look for that specifically causes that click or specifics brands that do that vs. others. I was looking at the Rosen 5JR vs. the 5JR express - the 5JR exp has no boning and doesn't have the "indent" (for lack of a better word) in the trigger guard. Is it the boning that causes better retention and/or the "click" or is it something else? Does boning have any effect on retention? Rosen standard models have indents on trigger guard, 5-shot leathers have the indent on the trigger guard, High-noon does, milt sparks does, JRC looks like it has it on some models, Kramer doesn't, Alessi does. I mention those specific manufacturers because they are either well regarded on this forum or they make holsters in horsehide which seems to be thinner and more concealable. I still haven't figure out if that matters to me. Anyways anyone have any thoughts on this?
For quick reference one example:
5JR - Regular
5JR - Express
ETA - the boning also looks like it is deeper around the ejection port too - not sure if this has any effect either.
