Sounds like you've put alot of time/thoughtinto your choices.
To simplify things even further.
You could have choosen a LW revolver that matchs the power level of your belt carried firearm while not increasing the weight of your pocket gun.
With this system you have now simplified things down to one gun for both pocket and belt carry and increased the power of your pocket gun.
.22 conversion kits are available forSig, Beretta, Glock, 1911 variants andEAA (Witness) just to name a few.
However, your system does have one advantage.
You have two guns you could carry a CC'd pocket gun and OC'ed belt gun.
Welcome to OCDO.
Might I suggest changing the grips on your pocket gun from rubber(they appear to be)to a hard plastic or wood.
IMHO, rubber grips are bad for pocket or CC under light garments they are too clingy.
