:-). That could be I suppose. He didn’t say he dropped it. He said he picked it up and it went off. He probably hit the trigger by mistake. I’ve only personally been around two, my sister’s and the one my husband traded for. He said the trigger pull on his was so light that it made him very nervous so he got rid of it. He prefers his 9mm Ruger. My sister does OK with hers because she practices with it all the time but she will be the first to tell you that the trigger is too light for most people. I prefer a stronger trigger pull myself.
Melinda I’ve handled dozens of Glocks and have never found the trigger pull to be excessively light.
The only way it could be extra light is if it was modified unless you are comparing it to handguns with extra heavy trigger pull.
But if you like harder or longer trigger pulls that’s a matter of perference but it’s still a long way off from implying that Glocks have hair triggers.
He probably put his finger on the trigger out of habit, doubt he hit it. The Glock has a safety built into the trigger. The trigger is split, with a very "small finger" between the split. When you place your finger on the trigger the "small finger" is naturally depressed releasing the safety.
From the Glock website, http://www.glock.com/english/index_options.htm look under "connector". They offer 3 different trigger pulls, 4.5, 5.5 and 8.0 LBS. My G23 / 40 Cal has the 5.5 pound pull, if owners feel the 5.5 too light, then take it a gunsmith and have the connector replaced with the 8.0.
From the pix your sister shoots competition, the handgun is a 1911 or variant, cal could be 9mm, 38 super, 40 or 45. Comp guns have very light trigger pulls.
