wishicould,
A Glock really should be carried in hard holster with covered trigger-guard, (leather, kydex, or otherwise); but not soft suede or nylon.
As to best position for carry, it is really a matter of personal experimentation. What works best for me (3:30) may not work for you since everyone's physical build, degree of manual dexterity, and comfort level is different. You will also find that the exact same pistol, holster, and concealing top garment will work great with one pair of pants and conceal dramatically differently with another. Since jeans tend to ride lower on the waist than Dockers or dress pants, the ride height of the holster can change as much as an inch; and this can change concealment and draw. A good recommendation for comfort when carrying IWB is to get a few pairs of pants dedicated to concealment that are one-inch waist size larger than you normally wear to leave additional room for the holstered pistol. As to overcoming the fear of a loaded chamber, familiarity and experience with your firearm will alleviate this, but the best advice I can give is to invest in some training. A course at one of the well-known schools is not cheap, but once you have the proper equipment, going to one of the better known shooting schools is some of the best money you will spend having made the decision to carry concealed. If there is not a trainer locally in your area, check the on-line course curriculum. Most of the major schools offer off-site courses at different areas throughout the country during the year. It amazes me the number of guys I see who buy a gun a week and blast away at the local range, not shooting very well, and their basic gun-handling and manipulation skills are awful. If they invested half the money they just spent on guns and ammo on one good training course, their proficiency would increase dramatically; not just in shooting but in safe gun-handling. Many of the better schools are not markmanship courses, but concentrate on safe firearms manipulation, tactics, and self defense.
Good luck with your new-found interest, and please feel free to
