I carried several guns in my 30 years of law enforcement, ended up with the Glock 22 .40 S&W for the last 10 years. Carried it after retirement, but ended up leaving it in the car most of the time cause of size. Carried a Mauser hsc .380 off duty and after retirement. Going to sell that. Also had a pocket .25 for shorts/t-shirt weather. Sold two Colt Pythons, a 4" and a 2 1/2", going to sell the Mauser and .25 now too. Gave my son the Glock cause I promised him it was his when I didn't want it anymore.
So, I bought the Ruger LCP .380 for summer carry and the Ruger LC9 9mm for winter. Not like the Glock .40, but the 9mm is the same size as the Mauser .30 and the LCP .380 is the same size as the old .25 I carry in my pocket. For personal protection, they'll be fine - not a cop anymore so don't really need the stopping power/number of rounds nor distance shooting I needed on the job. Not going to be shooting anything except up very close for personal protection - ha, I hope???
BTW, Illinois is only one of two states that doesn't have some sort of concealed carry, along with Wisconsin, but I think I hear WI is now authorizing some form of CC carry?? Since I'm retired LE, I can carry anywhere in the US under Federal rules
