• Dry the chamber and bore by pushing a lint-free cotton patch through the chamber and bore with the brush. Keep changing the patch until it emerges clean. • Lightly oil the threaded barrel stud. RECOIL SPRINGS and SPRING GUIDE • Lightly oil the recoil spring (Fig. 15-M), firing pin guide (Fig. 15-N), firing pin spring (Fig. 15-P) and firing pin (Fig. 15-Q) with Beretta oil or another good grade gun oil. After long use, it may be necessary to clean these parts first using a good quality cleaning brush. SLIDE • Clean the slide with Beretta oil or another good grade gun oil, paying special attention to the breech face, extractor and the slide surfaces that engage the receiver (Fig. 18). If necessary, use a good quality cleaning brush to remove built-up dirt. Dry the parts carefully with a clean, lint-free cotton patch. • Lightly lubricate the slide by applying a small drop of oil to the slide surfaces that engage the receiver and the extractor. RECEIVER • Clean the receiver with a soft, lint-free cotton patch. CAUTION: Do not use acids, water and chlorinated solvents. CAUTION: Do not apply excess oil. Accumulation of oil attracts dirt and dust, which can interfere with the functioning and reliability of the pistol. 32
