FBI selects new pistol to go with its 9mm ammo

[Valmet]

FYI : I will pass on what a border patrol agent of 11 yrs in service at that time told me several yrs ago .
They had glocks for " ONE " yr , only, then dumped them . Why ? well it seems that when you were in an extended firing session the mags ( made of plastic , or something like it ) literally " welded " themselves to the inside of the heated gun . He told me that they used screwdrivers and pocket knives trying to remove the mag's . They completely tore the mags to bit and pieces and still couldn't get them removed . They contacted glock and got " nowhere " so they dumped the glocks and went to HK's . Problem solved . An expensive fix to a cheap problem was his final comment .

Definitely sounds like this BP "veteran" was feeding you a huge pile of BS. Additionally with Glocks dealings with PDs, foreign govt's and US Gov't agencies it's highly unlikely they would simply tell the BP Agency to pound sand if they were actually experiencing those type of problems.
