Glocks are particularly dangerous to the untrained, incompetent, impaired and complacent. if you aren't in the habit of practicing proper trigger discipline and don't pay proper attention when holstering, you do increase your chance of of an accidental/negligent discharge. Most individuals can handle Glocks without accidentally putting holes where they don't belong. Glocks and similar striker fired handguns now dominate the LE and Military market. While the skill and discipline of MiL and LE vary greatly by organization and individual and there have been a number of AD/NDs the majority are able to handle their service pistols without self selecting.

As mentioned above, select a good quality holster that covers the trigger guard and remember that there is no prize for fast holstering. A number of the AD's I've read about have occurred when something gets into the trigger during holster.

Two other options, modify the G26 or look at another make/model. If the stock glock trigger pull (5.5-6 lbs) is too light for your taste, have a Glock armorer replace the trigger spring and connector which should get you an 8lb trigger pull. While that is still lighter than a DA revolver, it might make you more comfortable.

Both the SIG P365 and S&W Shield can be had with manual safeties. While the P365 will be more expensive then the G26, you get the same number of rounds in a thinner package and the option of a manual safety. The S&W Shield can be purchased at a very competitive price with a manual safety as well. The standard shield only holds 7 or 8 in the magazine, but the new Shield plus holds 10 or 13.

Or for Bonus Points, get yourself a 3913 or 6906, IMHO of the best IMHO 3rd GEN S&W compact Semi autos.

YMMV.
