It seems that many of the Model 1900's were adopted by police agencies. I also have one, and have disassembled it several times to inspect and marvel at the machining. Very close tolerances, and exceptional surface finish.
I bought mine through GB, IIRC for about $325...I was somewhat dismayed when it arrived and I saw how small it really is...The proportions are so balanced that photos don't show that it is about 3/4 the size of a M1911...
I would have been happier if it was bulkier, but it is what it is...
