I have two quality GALCO holsters for my new GLOCK 21. Fit and finish are great. The problem is that although neither is lined, the inside is a rough suede. The suede is so rough, the gun is hard to pull from the holster. My question is: will any product slick up the leather without making the complete holster turn softer than a paper towel and loose it's molded form? Any feedback will be much appreciated. Thanks in advance.
