Question for those of you who are avid users of the Nelson wraparound design. Aside from the ease of threading the belt through the holster, are there any other benefits of using a snap trailing loop instead of the typical slot?

Examples of the traditional rear slot include the Sparks 55BN, Alessi DOJ/ACP/PSS, 5 Shot CBS, Del Fatti SLP, Bulman SDS/FDS, etc.

Examples of the snap railing loop style include the Alessi DOJ/S and ACP/S, and the 5 Shot LFA-1.

I am wondering if the snap loop, which tends to extend further away, aids in pulling the butt of the pistol in towards the body even more.

Thanks in advance!
