We've covered this numerous times on this forum. The facts as summed up:
1) Since 2013, an observed 20-25% deadline rate on legacy P-series (P226, P229, etc) by various LE agencies across the country, many times involving cracked frames that cannot be predicted (i.e. sometimes crack within the first box of ammunition). Besides the 180-man department I detailed in prior threads, both @
AMC and @
Lon can detail this at their departments as well.
2) High profile incidents of problems since 2013:
2a) the FAMS had to return three successive batches of P229s since 2013 due to non-functional guns, prompting their switch to buying guns off the CBP contract.
2b) NJSP getting an entire batch of P229s that were non-functional, prompting their return to manufacture, purchase of commercial-off-the-shelf Glocks, and subsequent lawsuit against SIG for failing to fulfill the contract terms when SIG tried blaming NJSP for using substandard ammunition (note: NJSP uses Speer Gold Dot for duty and Speer Lawman for training, so, bullpucky).
