11-round (2) and 15-round (1) magazines were actually issued to Agents along with the 1076. Agents carried the two 11-round magazines in their magazine pouchs. It was impractical to carry the 15-round magazine for obvious reasons. Agents were allowed to use the 11-round mags in qualifying but not the 15-round mag. Bureau documents indicate that the FBI 1076 experienced unacceptable feeding problems with the 15-round mag and it is unclear if those problems were ever remedied. The 15-round mag was never offered for public sale and is extremely rare these days.
